getParameterSchema

public org.apache.arrow.vector.types.pojo.Schema getParameterSchema()
                                                             throws AdbcException

Description copied from interface: AdbcStatement

Get the schema for bound parameters.

This retrieves an Arrow schema describing the number, names, and types of the parameters in a parameterized statement. The fields of the schema should be in order of the ordinal position of the parameters; named parameters should appear only once.

If the parameter does not have a name, or the name cannot be determined, the name of the corresponding field in the schema will be an empty string. If the type cannot be determined, the type of the corresponding field will be NA (NullType).

This should be called after AdbcStatementPrepare.

Specified by:

getParameterSchema in interface AdbcStatement

Throws:

AdbcException - with AdbcStatusCode.NOT_IMPLEMENTED if the parameters cannot be determined at all.

prepare

public void prepare()
             throws AdbcException

Description copied from interface: AdbcStatement

Turn this statement into a prepared statement.

Call AdbcStatement.executeQuery(), AdbcStatement.executeUpdate(), or AdbcStatement.executePartitioned() to execute the query.

Specified by:
