Overview
You can turn SQL logging on when launching by using -DEOAdaptorDebugEnabled=true or EOAdaptorDebugEnabled YES. However, this can slam out a ton of SQL. While this is useful for some debugging it is way too much to sift through when trying to analyze a particular problem.
You can use this method to selectively enable and disable SQL logging:
public static void logSQL(boolean shouldLog) {
if (shouldLog) {
NSLog.allowDebugLoggingForGroups(NSLog.DebugGroupSQLGeneration |
NSLog.DebugGroupDatabaseAccess |
NSLog.DebugGroupEnterpriseObjects);
} else {
NSLog.refuseDebugLoggingForGroups(NSLog.DebugGroupSQLGeneration |
NSLog.DebugGroupDatabaseAccess |
NSLog.DebugGroupEnterpriseObjects);
}
}
This can be useful for such things as determining what fetches are performed when a page is rendered:
public void appendToResponse(WOResponse aResponse,
WOContext aContext) {
logSQL(true);
super.appendToResponse(aResponse, aContext);
logSQL(false);
}
