FunctionStatement

public FunctionStatement(Connection con,
                         String databaseName,
                         String procedureName,
                         String arguments,
                         ReentrantLock lock,
                         boolean canUseServerTimeout,
                         boolean canUseServerMaxRows,
                         boolean canCachePrepStmts,
                         int resultSetType,
                         int resultSetConcurrency)
                  throws SQLException

Constructor of function callable statement

Parameters:

con - current connection

databaseName - database

procedureName - procedure

arguments - arguments

lock - thread lock object

canUseServerTimeout - can use server timeout

canUseServerMaxRows - can use server max rows

canCachePrepStmts - can cache server prepared result

resultSetType - result set type

resultSetConcurrency - concurrency type

Throws:

SQLException - if any error occurs

Method Detail

isFunction

public boolean isFunction()

Description copied from class: BaseCallableStatement

Indicate if callable statement is a function or a stored procedure

Specified by:

isFunction in class BaseCallableStatement

Returns:

indicate if is a function

handleParameterOutput

protected void handleParameterOutput()
                              throws SQLException

Overrides:

handleParameterOutput in class ServerPreparedStatement

Throws:

SQLException

registerOutParameter

public void registerOutParameter(int index,
                                 int sqlType)
                          throws SQLException

Description copied from class: BaseCallableStatement

Registers the OUT parameter in ordinal position parameterIndex to the JDBC type sqlType. All OUT parameters must be registered before a stored procedure is executed.

The JDBC type specified by sqlType for an OUT parameter determines the Java type that must be used in the get method to read the value of that parameter.

If the JDBC type expected to be returned to this output parameter is specific to this particular database, sqlType should be java.sql.Types.OTHER. The method BaseCallableStatement.getObject(int) retrieves the value.

Specified by:

registerOutParameter in interface CallableStatement

Overrides:

registerOutParameter in class BaseCallableStatement

Parameters:

index - the first parameter is 1, the second is 2, and so on

sqlType - the JDBC type code defined by java.sql.Types. If the parameter is of JDBC type NUMERIC or DECIMAL, the version of registerOutParameter that accepts a scale value should be used.

Throws:

SQLException - if the parameterIndex is not valid; if a database access error occurs or this method is called on a closed CallableStatement

SQLFeatureNotSupportedException - if sqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type

executeInternal

protected void executeInternal()
                        throws SQLException

Description copied from class: ServerPreparedStatement

Throws:

SQLException - if any error occurs

preValidParameters

protected void preValidParameters()
                           throws SQLException

Ensures that returning value is not taken as a parameter.

Throws:

SQLException - if any exception

toString

public String toString()

Overrides:

toString in class ServerPreparedStatement
