|
void |
clearWarnings()
Clears all the warnings reported on this Statement object.

Executes the given SQL statement, which may return multiple results.
|
boolean |
execute(java.lang.String sql,

if the result is a ResultSet object or there are no more results, -1 is returned.
|
java.sql.SQLWarning |
getWarnings()
Retrieves the first warning reported by calls on this Statement object.
|
void |
setCursorName(java.lang.String name)
Sets the SQL cursor name to the given String, which will be used by subsequent Statement object execute methods.
|
void |
setEscapeProcessing(boolean enable)
Sets escape processing on or off.
