    public abstract class StatementCreatorUtils

extends Object

Utility methods for PreparedStatementSetter/Creator and CallableStatementCreator implementations, providing sophisticated parameter management (including support for LOB values).

Used by PreparedStatementCreatorFactory and CallableStatementCreatorFactory, but also available for direct use in custom setter/creator implementations.

### StatementCreatorUtils

    public StatementCreatorUtils()

Method Detail

### javaTypeToSqlParameterType

    public static int javaTypeToSqlParameterType(Class javaType)

  Derive a default SQL type from the given Java type.

  Parameters:
    `javaType` - the Java type to translate
  Returns:
    the corresponding SQL type, or `null` if none found

### setParameterValue

    public static void setParameterValue(PreparedStatement ps,
                                         int paramIndex,
                                         SqlParameter param,
                                         Object inValue)
                                  throws SQLException

  Set the value for a parameter. The method used is based on the SQL type of the parameter and we can handle complex types like arrays and LOBs.

  Parameters:
    `ps` - the prepared statement or callable statement
    `paramIndex` - index of the parameter we are setting
    `param` - the parameter as it is declared including type
    `inValue` - the value to set
  Throws:
    `SQLException` - if thrown by PreparedStatement methods

### setParameterValue

    public static void setParameterValue(PreparedStatement ps,
                                         int paramIndex,
                                         int sqlType,
                                         Object inValue)
                                  throws SQLException

  Set the value for a parameter. The method used is based on the SQL type of the parameter and we can handle complex types like arrays and LOBs.

  Parameters:
    `ps` - the prepared statement or callable statement
    `paramIndex` - index of the parameter we are setting
    `sqlType` - the SQL type of the parameter
    `inValue` - the value to set (plain value or a SqlTypeValue)
  Throws:
    `SQLException` - if thrown by PreparedStatement methods
  See Also:
    `SqlTypeValue`

### setParameterValue

    public static void setParameterValue(PreparedStatement ps,
                                         int paramIndex,
                                         int sqlType,
                                         String typeName,
                                         Object inValue)
                                  throws SQLException

  Set the value for a parameter. The method used is based on the SQL type of the parameter and we can handle complex types like arrays and LOBs.

  Parameters:
    `ps` - the prepared statement or callable statement
    `paramIndex` - index of the parameter we are setting
    `sqlType` - the SQL type of the parameter
    `typeName` - the type name of the parameter (optional, only used for SQL NULL and SqlTypeValue)
    `inValue` - the value to set (plain value or a SqlTypeValue)
  Throws:
    `SQLException` - if thrown by PreparedStatement methods
  See Also:
    `SqlTypeValue`

### cleanupParameters

    public static void cleanupParameters(Object[] paramValues)

  Clean up all resources held by parameter values which were passed to an execute method. This is for example important for closing LOB values.

  Parameters:
    `paramValues` - parameter values supplied. May be `null`.
  See Also:
    `DisposableSqlTypeValue.cleanup()`, `SqlLobValue.cleanup()`

### cleanupParameters

    public static void cleanupParameters(Collection paramValues)

  Clean up all resources held by parameter values which were passed to an execute method. This is for example important for closing LOB values.

  Parameters:
    `paramValues` - parameter values supplied. May be `null`.
  See Also:
    `DisposableSqlTypeValue.cleanup()`, `SqlLobValue.cleanup()`
