List of newLiteral() Examples

Examples of newLiteral()

org.datanucleus.store.mapped.mapping.JavaTypeMapping.newLiteral()

Creates a literal from an value for use in TJDO-style JDOQL. This implementation just throws a NucleusException. @param qs The Query statement @param value The object @return A Scalar Expression

org.datanucleus.store.rdbms.sql.expression.SQLExpressionFactory.newLiteral()

Factory for a literal representing a value. To create a NullLiteral pass in a null mapping. @param stmt The statement @param mapping The mapping @param value The value @return The literal

org.jpox.store.mapped.mapping.JavaTypeMapping.newLiteral()

Creates a literal from an value. A string literal is enclosed in single quotes. for example: "literal". A string literal that includes a single quote is represented by two single quotes. for example: "literal''s". An exact numeric literal is a numeric value without a decimal point, such as 57, -957, +62. An approximate numeric literal is a numeric value in scientific notation, such as 7E3, -57.9E2, or a numeric value with a decimal, such as 7., -95.7, +6.2. @param qs The Query statement @param value The object @return A Scalar Expression

            stmt.getTableExpression(collectionTableAlias));
        stmt.andCondition(ownerExpr.eq(ownerInCollectionExpr));


        // Select COUNT(*)
        JavaTypeMapping m = dba.getMapping(String.class, storeMgr);
        StringLiteral lit = (StringLiteral)m.newLiteral(stmt, "COUNT(*)");
        lit.generateStatementWithoutQuotes();
        stmt.selectScalarExpression(lit);


        // TODO This needs to restrict the discriminator also where it is present (see sizeStmt)

Examples of org.jpox.store.mapped.mapping.JavaTypeMapping.newLiteral()

        ScalarExpression ownerInCollectionExpr = ownerMapping.newScalarExpression(stmt, stmt.getTableExpression(mapTableAlias));
        stmt.andCondition(ownerExpr.eq(ownerInCollectionExpr));


        // Select COUNT(*)
        JavaTypeMapping m = dba.getMapping(String.class, storeMgr);
        StringLiteral lit = (StringLiteral)m.newLiteral(stmt, "COUNT(*)");
        lit.generateStatementWithoutQuotes();
        stmt.selectScalarExpression(lit);


        return stmt;
    }
