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
