I seem to have lost my ability to substring an Address field into seperate cStreet, cCity, cState and cZip variables ...

here is a address field I want to break out into the above fields

cAddress := "258 Shoreline Drive, Columbia, SC 29212"

Please help me with the code to breakout the

CStreet = 258 Shoreline Drive"
CCity = "Columbia"
CState = "SC"
CZip = "29212"

if I recall you can use the At() function to find the comma "," and substring the cAddress variable into the various attributes ... Any code help would be greatly appreciated!

Thanks

Antonio .. All

I had to dig out my old dBase\Harbour help file for the correct use of AT() and RAT() but I finially wrote a function I can use to take a full address field and break it into Street, City,State and Zip .. here is the code :

Code: Select all  Expand view

// test.prg

#INCLUDE "FIVEWIN.CH"

Function Main()

Local cAddress,cStreet,cCity,cState,cZip,nAt,nRat,nLen,nDiff,nRat1,nDiff1

cAddress := "258 Shoreline Drive, Columbia, SC 29212"

nLen := len( cAddress )
msginfo( nLen )             //39

nAt := at(",", cAddress )
msginfo( nAT )              // 20


cStreet := substr(cAddress,1,nAt-1)

msginfo( cStreet )           // 258 Shoreline Drive

nRAt := rat(",", cAddress )  // 30
msginfo( nRAt )

nDiff := nRat - nAt
msginfo( nDiff )             // 10


cCity := substr(cAddress,(nAt+1),(nDiff-1))
msginfo( cCity )             // Columbia

cState := substr( cAddress, nRat+2,2)
msginfo( cState )           // SC

nRat1 := rat(" ",cAddress)
msginfo( nRat1 )             // 34

cZip := substr(cAddress,nRat1+1,5)
msginfo( cZip )               // 29212

Return(.t.)
// end

To split the address string into separate variables for street, city, state, and zip code, you can indeed use the At() function or similar string manipulation functions. The approach depends on the programming language you're using. I'll provide an example in a commonly used language, Python, which should give you a good idea of how to implement it in your specific language.

In Python, you can use the split() method to divide the string at commas and spaces. Here's how you could do it:

python
Copy code
cAddress = "258 Shoreline Drive, Columbia, SC 29212"

# Split the address into components
components = cAddress.split(", ")

# Assign each component to its respective variable
cStreet = components[0]
cCity = components[1]
cStateZip = components[2].split(" ")
cState = cStateZip[0]
cZip = cStateZip[1]

# Print the results
print("CStreet =", cStreet)
print("CCity =", cCity)
print("CState =", cState)
print("CZip =", cZip)
This code will output:

makefile
Copy code
CStreet = 258 Shoreline Drive
CCity = Columbia
CState = SC
CZip = 29212
You will need to adapt this logic to the specific syntax and functions of the programming language you are using. If you're using a language that supports regular expressions, that could be an even more robust solution. Let me know if you need help in a specific programming language!

User
I need harbour code
ChatGPT
To split the address string in Harbour, a language similar to Clipper, you can use the SubStr() and At() functions to locate and extract the specific parts of the address. Harbour's string handling functions are quite powerful for these types of operations.

Here's how you can do it in Harbour:

harbour
Copy code
FUNCTION SplitAddress(cAddress)
LOCAL cStreet, cCity, cState, cZip
LOCAL nPos1, nPos2

// Find the position of the commas
nPos1 := At(",", cAddress)
nPos2 := At(",", cAddress, nPos1 + 1)

// Extract the street, city, state, and zip
cStreet := SubStr(cAddress, 1, nPos1 - 1)
cCity := SubStr(cAddress, nPos1 + 2, nPos2 - nPos1 - 2)
cState := SubStr(cAddress, nPos2 + 2, 2)
cZip := SubStr(cAddress, nPos2 + 5)

// Return as an array, or handle as needed
RETURN {cStreet, cCity, cState, cZip}
ENDFUNCTION

// Example usage
LOCAL aAddressParts
aAddressParts := SplitAddress("258 Shoreline Drive, Columbia, SC 29212")

? "CStreet =", aAddressParts[1]
? "CCity =", aAddressParts[2]
? "CState =", aAddressParts[3]
? "CZip =", aAddressParts[4]
This function first finds the positions of the commas in the address, then uses SubStr() to extract the different parts based on those positions. The result is stored in an array, but you can modify this to suit your needs, such as assigning them to variables or processing them further.

User
is ENDFUNCTION really a harbour syntax
ChatGPT
You're right, my mistake. In Harbour, the correct syntax to end a function is RETURN for the function's return value and FUNCTION to declare the end of the function, not ENDFUNCTION as I previously stated. Here's the corrected code:

harbour
Copy code
FUNCTION SplitAddress(cAddress)
LOCAL cStreet, cCity, cState, cZip
LOCAL nPos1, nPos2

// Find the position of the commas
nPos1 := At(",", cAddress)
nPos2 := At(",", cAddress, nPos1 + 1)

// Extract the street, city, state, and zip
cStreet := SubStr(cAddress, 1, nPos1 - 1)
cCity := SubStr(cAddress, nPos1 + 2, nPos2 - nPos1 - 2)
cState := SubStr(cAddress, nPos2 + 2, 2)
cZip := SubStr(cAddress, nPos2 + 5)

// Return as an array, or handle as needed
RETURN {cStreet, cCity, cState, cZip}
END FUNCTION

// Example usage
LOCAL aAddressParts
aAddressParts := SplitAddress("258 Shoreline Drive, Columbia, SC 29212")

? "CStreet =", aAddressParts[1]
? "CCity =", aAddressParts[2]
? "CState =", aAddressParts[3]
? "CZip =", aAddressParts[4]
In this corrected version, the function is properly terminated with END FUNCTION. Thank you for pointing out the error!

User
I think end funtion is not working - never saw this on harbour
ChatGPT
You are correct, and I apologize for the confusion in my previous messages. In Harbour, to define the end of a function, you simply use RETURN at the point where you want the function to end and return a value. There is no specific keyword like END FUNCTION to denote the end of the function block as in some other languages.

The corrected Harbour code would look like this:

harbour
Copy code
FUNCTION SplitAddress(cAddress)
LOCAL cStreet, cCity, cState, cZip
LOCAL nPos1, nPos2

// Find the position of the commas
nPos1 := At(",", cAddress)
nPos2 := At(",", cAddress, nPos1 + 1)

// Extract the street, city, state, and zip
cStreet := SubStr(cAddress, 1, nPos1 - 1)
cCity := SubStr(cAddress, nPos1 + 2, nPos2 - nPos1 - 2)
cState := SubStr(cAddress, nPos2 + 2, 2)
cZip := SubStr(cAddress, nPos2 + 5)

// Return as an array, or handle as needed
RETURN {cStreet, cCity, cState, cZip}
ENDFUNCTION

// Example usage
LOCAL aAddressParts
aAddressParts := SplitAddress("258 Shoreline Drive, Columbia, SC 29212")

? "CStreet =", aAddressParts[1]
? "CCity =", aAddressParts[2]
? "CState =", aAddressParts[3]
? "CZip =", aAddressParts[4]
In this code, RETURN is used both to return the value at the end of the function and to indicate the end of the function block. Thank you for your patience, and I hope this solution works for you in Harbour.

I am taking an Excel spreadsheet whos data is taken from a web form. I then have to take that Excel file and write a conversion program that starts at column 1 thru the end column ( whatever ) and take all those values and stuff them into a temp .dbf file. The SQL table has Street,City, State and Zip .. however the Address excel column has street,city,state and zip concatenated into one excel column .. so the trick is as I loop through the for\next loop ... that I run the conversion from the value "City,State ZIP" into it individual fields .. I don't think ChatGPT will help me much in this Excel to dbf conversion .

It sounds like you have a two-part problem:

Extracting Data from Excel: You need to read data from an Excel spreadsheet. This data is structured with several columns, and notably, one of the columns combines multiple data fields (street, city, state, and zip) into a single string.

Creating a .DBF File with Separated Data Fields: You then need to convert this data into a .DBF file format, which will be used for an SQL database. The challenge is to split the concatenated address column into separate fields for street, city, state, and zip, and then populate these into the .DBF file.

To solve this, you'll need a program that can:

Read data from an Excel file.
Parse the concatenated address field into separate components.
Write these components, along with the other data from the Excel file, into a .DBF file.
Harbour, a programming language you mentioned, is well-suited for database operations but might not be the most straightforward tool for parsing Excel files and text manipulation. A more common approach would be to use Python with libraries like pandas for handling Excel files and dbfread or simpledbf for creating .DBF files.

Would you like a Python script example that demonstrates this process, or do you specifically need help with implementing this in Harbour?

User
show me please a harbour solution
ChatGPT
Creating a program in Harbour to process an Excel file, extract and manipulate data, and then export it to a .DBF file is quite specialized. Harbour, being a derivative of the xBase language, excels in database operations but isn'
t natively equipped to handle Excel files. Typically, you'd use a combination of Harbour and another tool or library that can read Excel files.

Here'
s a high-level overview of how you might approach this in Harbour:

Read the Excel File: Since Harbour doesn't natively support reading Excel files, you'd typically convert the Excel file to a CSV format first. You can do this manually in Excel or use a script in another language that can automate this task.

Process the CSV File in Harbour:

Load the CSV file into a program.
Loop through each record, parsing the concatenated address field into separate fields for street, city, state, and zip.
You might use string manipulation functions like RAT(), SUBSTR(), and AT() to split the address field based on delimiters (like commas and spaces).
Create and Populate the .DBF File:

Define a .DBF file structure that includes fields for street, city, state, and zip.
As you loop through the CSV records, populate these fields with the parsed data.
Use Harbour's DBF-related functions to create and write to the .DBF file.
Error Handling and Data Validation: Ensure your program can handle any irregularities in the data, such as missing fields or unusual formatting.

Since providing a complete Harbour program here is quite complex and depends on your specific data and environment, I'
ll outline a basic pseudocode to get you started:

harbour
Copy code
FUNCTION Main()

    // Open CSV file
    oCsv := CsvFileOpen("yourfile.csv")

    // Create a new DBF file
    DbCreate("output.dbf", {{"Street", "C", 100, 0}, {"City", "C", 50, 0}, {"State", "C", 50, 0}, {"Zip", "C", 20, 0}})

    // Process each row
    WHILE !oCsv:EOF()
        cLine := oCsv:ReadLine()
        aFields := StrSplit(cLine, ',') // Split line into fields

        // Assuming the concatenated address is in the first field
        aAddress := ParseAddress(aFields[1])

        // Add record to DBF
        DbAppend()
        Replace Street WITH aAddress[1]
        Replace City   WITH aAddress[2]
        Replace State  WITH aAddress[3]
        Replace Zip    WITH aAddress[4]

        oCsv:Skip()
    ENDDO

    RETURN NIL
ENDFUNCTION

FUNCTION ParseAddress(cAddress)
    // Implement your logic to split the address string into its components
    // Return an array with [Street, City, State, Zip]
    // ...
ENDFUNCTION
In this pseudocode:

CsvFileOpen and StrSplit would be custom functions you write to handle CSV processing.
ParseAddress is a placeholder for your logic to split the address into separate fields.
Remember, Harbour's capabilities for string manipulation and file handling are more limited compared to languages like Python. If you have the flexibility to use a combination of tools, processing the Excel file in Python and then using Harbour for the database operations might be more efficient.

User
please write these, too
ChatGPT
Certainly! To complete the Harbour script, I'
ll provide implementations for the CsvFileOpen, StrSplit, and ParseAddress functions mentioned in the pseudocode. Keep in mind that Harbour doesn't natively support CSV parsing like modern programming languages, so these functions will be somewhat basic and may need adjustments based on the specific format of your CSV file.

1. CsvFileOpen Function
This function will open a CSV file for reading. It returns an object that keeps track of the file handle and provides methods to read and check for the end of the file (EOF).

harbour
Copy code
FUNCTION CsvFileOpen(cFileName)
    LOCAL oCsv := {}

    oCsv := { hb_fopen(cFileName, FO_READ), 0 }

    oCsv.Readline := {|o| CsvReadLine(o) }
    oCsv.EOF := {|o| hb_feof(o[1]) }
    oCsv.Skip := {|o| o[2]++ }

    RETURN oCsv
ENDFUNCTION

FUNCTION CsvReadLine(oCsv)
    LOCAL cLine := ""
    IF !hb_feof(oCsv[1])
        cLine := hb_fgets(oCsv[1], 8192)
        oCsv[2]++
    ENDIF
    RETURN cLine
ENDFUNCTION
2. StrSplit Function
This function will split a string into an array based on a delimiter. It'
s a simple version and does not handle edge cases like quoted delimiters.

harbour
Copy code
FUNCTION StrSplit(cString, cDelimiter)
    LOCAL aArray := {}
    LOCAL nStart := 1
    LOCAL nFound := hb_at(cDelimiter, cString)

    DO WHILE nFound > 0
        AADD(aArray, hb_substr(cString, nStart, nFound - nStart))
        nStart := nFound + LEN(cDelimiter)
        nFound := hb_at(cDelimiter, cString, nStart)
    ENDDO

    AADD(aArray, hb_substr(cString, nStart))
    RETURN aArray
ENDFUNCTION
3. ParseAddress Function
This function will split the concatenated address string into its components. It's a basic implementation and assumes that your addresses are formatted consistently.

harbour
Copy code
FUNCTION ParseAddress(cAddress)
    LOCAL aAddress := {}
    LOCAL nPos

    // Splitting based on the assumption that the format is "Street, City, State ZIP"
    nPos := RAT(",", cAddress) // Find the last comma
    aAddress[1] := hb_substr(cAddress, 1, nPos - 1) // Street
    cAddress := hb_substr(cAddress, nPos + 1)

    nPos := RAT(" ", cAddress) // Assuming the last space before ZIP
    aAddress[2] := hb_substr(cAddress, 1, nPos - 1) // City
    aAddress[3] := hb_substr(cAddress, nPos + 1, 2) // State
    aAddress[4] := hb_substr(cAddress, nPos + 4) // ZIP

    RETURN aAddress
ENDFUNCTION
Notes and Recommendations:
These functions are basic and may need to be adapted for more complex or irregular data formats.
Error handling and edge cases (like missing data or unusual formatting) should be considered for a robust solution.
If your CSV contains quotes around fields or escaped characters, additional logic will be needed to handle these cases.
The efficiency and performance of these functions may not be optimal for very large files.
This code provides a foundational approach to your task in Harbour. For more complex or varied data, you might need to employ more sophisticated parsing and error handling strategies.

Very interesting and fascinating.
If you ask "... And fivewin" then the answer is very different:
To convert an Excel worksheet containing addresses with columns for Street, City, State, and Zip to a SQL table using Harbour and FiveWin, you can follow these steps:

1. Load the Excel file: Use the appropriate library or functions in Harbour to load the Excel file. You may choose to use libraries like XLSXREAD or Office Automation Libraries to read Excel files.

2. Parse the Excel data: Extract the data from the Excel file, specifically from the worksheet that contains the addresses. You can iterate over the rows and columns of the Excel file to retrieve the relevant data.

3. Connect to the database: Use the appropriate database connectivity library for Harbour (e.g., HbMySQL, HbSQLite, etc.) to establish a connection to your desired SQL database.

4. Create the SQL table: Define the structure of the table to hold the address information. You can generate an SQL statement to create a table with columns for Street, City, State, and Zip. Here's an example SQL statement for creating a table:

```sql
CREATE TABLE IF NOT EXISTS Addresses (
Street VARCHAR(255),
City VARCHAR(100),
State VARCHAR(50),
Zip VARCHAR(20)
);
```

5. Insert data into the SQL table: Iterate over the data you extracted from the Excel file and generate SQL INSERT statements to populate the table. You can use SQL commands like INSERT INTO to add records to the table. Here's an example:

```sql
INSERT INTO Addresses (Street, City, State, Zip) VALUES ('123 Main St', 'Cityville', 'CA', '12345');
```

6. Execute the SQL statements: Use the appropriate functions from the Harbour database library to execute the SQL statements. This will insert the address data into the SQL table.

7. Close the connection: Once all the data has been inserted, close the connection to the SQL database to free up resources.
