public static StatementKey newPrepared(String sql,
                       String schema,
                       int holdability)

Creates a key for a query with default settings.

Defaults are according to the JDBC standard; result set type will be ResultSet.TYPE_FORWARD_ONLY, concurrency will be ResultSet.CONCUR_READ_ONLY and the statement will not return auto-generated keys.

Parameters:

sql - SQL query string

schema - current compilation schema

holdability - result set holdability

Returns:

A statement key.

newPrepared

public static StatementKey newPrepared(String sql,
                       String schema,
                       int holdability,
                       int autogeneratedKeys)

Creates a key for a query specifying whether auto-generated keys shall be returned.

Unspecified settings will be according to the JDBC standard; result set type will be ResultSet.TYPE_FORWARD_ONLY, concurrency will be ResultSet.CONCUR_READ_ONLY.

Parameters:

sql - SQL query string

schema - current compilation schema

holdability - result set holdability

autogeneratedKeys - tells whether or not to reutrn auto-generated keys

Returns:

A statement key.

newPrepared

public static StatementKey newPrepared(String sql,

                       int rsh)

Creates a key for a query specifying result set type and concurrency.

The returned key is for a statement not returning auto-generated keys.

Parameters:

sql - SQL query string

schema - current compilation schema

rst - result set type

rsc - result set concurrency level

rsh - result set holdability

Returns:

A statement key.

newCallable
