Returns or sets the SQL statement used to create the specified dynaset or OraSQLStmt
object. Not available at design time and read/write at run time.
SQL_statement = oradynaset.SQL SQL_statement = orasqlstmt.SQL oradynaset.SQL = SQL_statement orasqlstmt.SQL = SQL_statement
String
The first use returns the contents of the SQL statement buffer, and the second use sets the contents of the SQL statement buffer.
The SQL statement buffer initially contains the SQL statement used to create the dynaset or OraSQLStmt
object. The contents of the SQL statement buffer are executed whenever the Refresh
method is issued.
This example demonstrates the use of parameters, the Refresh
method, and the SQL property to restrict selected records. Copy and paste this code into the definition section of a form. Then, press F5.
