Description
The SQLPREPARE() function is used to prepare an SQL statement which will subsequently be executed by the SQLEXEC() function on the specified data source.
The SQLPREPARE() function operates on the data source specified by <nStatementHandle>.

| nStatementHandle | Statement handle to the connection. |
| cSQLCommand | The SQL statement to be passed to the data source. |
| cCursorName | The name of the cursor to use. If cCursorName is not specified, the default name SQLRESULT is used. |

|---|---|
| 1 | SQLPREPARE() successful |
| –1 | Connection error |
Example
nStatHand = sqlconnect("awhr") if nStatHand < 1 messagebox("Cannot make connection", 16, "SQL Connect Error") else messagebox("Connection made", 48, "SQL Connect Message") sqlexec(nStatHand,"create table doc1 (account_no char(5), lastname char(25), balance dec(10,2))") messagebox("Table created") m_accno = "00699" m_lastname = "Smith" m_balance = 12345.67 sqlexec(nStatHand,"insert into dbo.doc1 (account_no,lastname,balance) VALUES ('&m_accno','&m_lastname',&m_balance)") messagebox("Record inserted") nRet = sqlexec(nStatHand,"select * from dbo.doc1","mycursor") if nRet = -1 messagebox(sqlerror(nstatHand)) else messagebox("Record selected") list endif // Using prepared statement sqlprepare(nStatHand,"select * from dbo.doc1 where account_no = ?m_accno","mycursor") nRet = sqlexec(nStatHand) if nRet < 1 messagebox(sqlerror(nstatHand)) else messagebox("Record selected using prepared statement") list endif sqldisconnect(nStatHand) endif
