This article illustrates how to programmatically create table structures that correspond to SQL Server tables and copy the data from SQL Server to FoxPro tables. MORE INFORMATION ================ In situations where developers want to copy data from SQL Server tables to Visual FoxPro tables, you can use the SQLEXEC(), SQLTABLES(), and AFIELDS() functions for the following: - Retrieve information regarding the structure of SQL Server tables. - Create tables that correspond to SQL Server table structure(s). - Copy data from SQL Server tables to Visual FoxPro tables. The following code snippet illustrates the process of copying data from SQL Server tables to Visual FoxPro tables: Sample Code ----------- * Begin Code. * SQL Server Tables may contain long field names * that would not be supported in free tables. * Create a Database Container. CREATE DATABASE SQLDATA * Create a cursor to contain the table information. CREATE CURSOR SYS_Tables (Table_Name c(128), Field_Name c(120), ; Field_Type c(1), Field_len N(3,0), Field_Dec N(3,0)) * Create a connection string to connect to SQL Server. * Substitute the correct server name in the next line. Connect_String = 'DRIVER={SQL Server};SERVER=MY_SERVER;' + ; 'DATABASE=PUBS;UID=sa;PWD=' * Connect to SQL Server. gnConnHandle=SQLSTRINGCONNECT(Connect_String) IF gnConnHandle>0 * Want to use the PUBS Database, so send USE command. SQLCOMMAND="USE PUBS" =sqlexec(gnConnHandle,SQLCOMMAND) * Get the tables available on SQL Server. SQLConnTables=SQLTABLES(gnConnHandle) IF SQLConnTables>0 SELECT SQLResult * Only want tables, so select where table_type='TABLE' * Otherwise get system tables and views. SELECT Table_Name FROM SQLResult ; WHERE UPPER(ALLTRIM(Table_Type))="TABLE" ; INTO CURSOR SQL_Tables SELECT SQL_Tables INCnt=0 DO WHILE !EOF() * Create a command to execute the stored procedure. SQLCOMMAND="SELECT * FROM " + ALLTRIM(Table_Name) * Execute the stored procedure and return data to a cursor =sqlexec(gnConnHandle,SQLCOMMAND,'tmp_sys_data') * Select the cursor. SELECT tmp_sys_data * Get actual name of the tmp file that is in use with DBF() this_file=DBF() * Use AFIELDS() function to get fields and field attributes. =AFIELDS(test_vals) * Dimension maketab array to contain field data. DIMENSION maketab[alen(test_vals,1),6] * Load maketab array with field data. FOR i=1 TO ALEN(test_vals,1) maketab[i,1]=test_vals[i,1] maketab[i,2]=test_vals[i,2] maketab[i,3]=test_vals[i,3] maketab[i,4]=test_vals[i,4] maketab[i,5]=test_vals[i,5] maketab[i,6]=test_vals[i,6] NEXT * Create a table from the array maketab. Execute_Cmd="CREATE TABLE "+ALLTRIM(SQL_Tables.Table_Name)+ ; " FROM ARRAY maketab" &Execute_Cmd * Select the table that was just created. current_table=ALLTRIM(SQL_Tables.Table_Name) SELECT (current_table) * Append from the tmp file. APPEND FROM &this_file SELECT SQL_Tables SKIP ENDDO =SQLDISCONN(gnConnHandle) ENDIF ENDIF SELECT SQL_Tables CLOSE ALL USE AUTHORS BROWSE TIMEOUT 15 CLOSE ALL RETURN * End Code Copy the code snippet to a program file, then run the program file. The program creates a Database container named Sqldata.dbc and copies tables from the SQL Server PUBS database. After the tables are copied, the Authors table opens.
