SUMMARY
This article illustrates how to programmatically create table structures that correspond to tables in Microsoft Access Master Data Base (MDB) files. This article also illustrates how to copy the data in Microsoft Access tables to Visual FoxPro tables.



MORE INFORMATION
In situations where developers want to copy data from Microsoft Access tables to Visual FoxPro tables, the SQLTABLES, AFIELDS, and SQLEXEC functions may be used to:
 * Retrieve information regarding the number of tables contained in the MDB file.
 * Retrieve the names of tables in the MDB file.
 * Retrieve the structure of each of the tables contained in the MDB file.
 * Create tables that correspond to the structures of the identified tables.
 * Copy data from Microsoft Access tables to Visual FoxPro tables.

The following code snippet illustrates the process of copying data from Microsoft Access tables and information from the MDB file into Visual FoxPro tables. The code sample browses the Table_name field of the SQLResult cursor. LOCAL lcMyFile, lnConnHandle, lnResult, lcSQLCommand, lnGetData, lcNewName LOCAL ARRAY laWhatErr(1)

lcMyFile = GETFILE('MDB')

IF !EMPTY(lcMyFile) *!* Use a SQLStringConnect to connect to the MDB file lnConnHandle = ; SQLSTRINGCONNECT('DRIVER=MICROSOFT ACCESS DRIVER (*.MDB);DBQ=' + ;        lcMyFile) IF lnConnHandle > 0 *!* Need to know what tables are contained in the MDB file lnResult = SQLTABLES(lnConnHandle, 'TABLE') IF lnResult > 0 *!* Create a new DBC named &quot;MYNEW&quot; CREATE DATABASE mynew *!* Select SQLResult and scan through the cursor. SELECT SQLResult SCAN *!* Build a SQL SELECT statement to pass to SQLEXEC lcSQLCommand = ; &quot;SELECT * FROM [&quot; + ALLTRIM(SQLResult.table_name) + &quot;]&quot; lnGetData = SQLEXEC(lnConnHandle, lcSQLCommand, 'newdata') IF lnGetData > 0 *!* SQLEXEC was successful lcNewName = STRTRAN(ALLTRIM(SQLResult.table_name), &quot; &quot;, &quot;_&quot;)
 * !* No point if no MDB file is selected

SELECT newdata *!* Copy Table Structure and Data to a DBF file *!* VFP 3.0 - loses long field names *!* COPY TO (lcNewName) *!* ADD TABLE (lcNewName) *!* VFP 5.0/6.0 - keeps long field names COPY TO (lcNewName) DATABASE myNew ENDIF ENDSCAN ENDIF *!* Done Getting Data, so Disconnect =SQLDISCONNECT(lnConnHandle) ELSE *!* The SQLStringConnect failed =MESSAGEBOX('ODBC Connection Failed', MB_ICONEXCLAMATION, 'ODBC') *!* Call AERROR =AERROR(laWhatErr) *!* Display the error DISPLAY MEMORY LIKE laWhatErr ENDIF ENDIF
