Method Summary

Modifier and Type	Method and Description
void	appendTranslationParameter(java.io.Writer writer, ParameterExpression expression, DatabasePlatform platform, AbstractRecord record) INTERNAL: All values are printed as ? to allow for parameter binding or translation during the execute of the call.
boolean	hasCustomSQLArguments() INTERNAL: Used to avoid misinterpreting the # in custom SQL.
boolean	isQueryStringCall() Should return true.
boolean	isSQLCall()
void	setCustomSQLArgumentType(java.lang.String customParameterName, java.lang.Class type) PUBLIC: This method should only be used with custom SQL: it sets a type to IN, OUT or INOUT parameter (prefixed with #, ### or #### in custom SQL string).
void	setCustomSQLArgumentType(java.lang.String argumentFieldName, int type) PUBLIC: This method should only be used with custom SQL: it sets a type to IN, OUT or INOUT parameter (prefixed with #, ### or #### in custom SQL string).
void	setCustomSQLArgumentType(java.lang.String argumentFieldName, int type, java.lang.String typeName) PUBLIC: This method should only be used with custom SQL: it sets a type to IN, OUT or INOUT parameter (prefixed with #, ### or #### in custom SQL string).

void	setHasCustomSQLArguments(boolean hasCustomSQLArguments) INTERNAL: Used to avoid misinterpreting the # in custom SQL.
void	setSQLString(java.lang.String sqlString) Set the SQL string.
void	translateCustomQuery() INTERNAL: Keep track of the fact that this call has been translated.
void	translatePureSQLCustomQuery() INTERNAL: Only translate the call if it was not previously translated This code ensures the translation code for a custom SQLCall is only run once In the case of inheritance we will try to call the translation code once to get the list of types and again for each subclass

Constructor Detail

SQLCall

public SQLCall()

PUBLIC: Create a new SQL call.

SQLCall

public SQLCall(java.lang.String sqlString)

PUBLIC: Create a new SQL call. Warning: Allowing an unverified SQL string to be passed into this method makes your application vulnerable to SQL injection attacks.

Method Detail
