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
