Detailed Description

Dummy type representing a literal value for SQL operations.

Used by several methods in BpsDatastore and BpsSqlValues.

// Example
BpsSqlValues vals;
vals[bStr("c_key")] = BpsTypeLiteral(bStr("f_nextkey('testtable')"));
vals[bStr("c_text")] = bStr("some text");
 
q.prepare(
    bStr("insert into t_testtable (%1) values (%2)")
        .arg(vals.columns())
        .arg(vals.tags())
    // insert into t_table (c_key, c_text) values (f_nextkey('testtable'), ?)
);
q.execute(vals.values()); // "some text"
