Example 1 with DatabaseContext

use of org.apache.derby.iapi.db.DatabaseContext in project derby by apache.

the class SQLDate method setValue.

public void setValue(String theValue) throws StandardException {
    restoreToNull();
    if (theValue != null) {
        DatabaseContext databaseContext = (DatabaseContext) DataValueFactoryImpl.getContext(DatabaseContext.CONTEXT_ID);
        parseDate(theValue, false, (databaseContext == null) ? null : databaseContext.getDatabase(), (Calendar) null);
    }
}

Example 2 with DatabaseContext

use of org.apache.derby.iapi.db.DatabaseContext in project derby by apache.

the class SQLTime method setValue.

public void setValue(String theValue) throws StandardException {
    restoreToNull();
    if (theValue != null) {
        DatabaseContext databaseContext = (DatabaseContext) DataValueFactoryImpl.getContext(DatabaseContext.CONTEXT_ID);

    }
}

Example 3 with DatabaseContext

use of org.apache.derby.iapi.db.DatabaseContext in project derby by apache.

the class SQLTimestamp method setValue.

public void setValue(String theValue) throws StandardException {
    restoreToNull();
    if (theValue != null) {

    }
/* restoreToNull will have already set the encoded date to 0 (null value) */
}
