Method Detail

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
