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

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
