expression
of SqlDriver type type
.
The names are stored as an array of name components. The meaning of the
components depends upon the context in which the name is used. For example,
the name A.B in a select list would mean table.column, but in a constraint
or index context, it would mean column.attribute as table.column is invalid
in such a context.
expression
- the arithmetic expression to be parsed for column namestype
- an expression type defined in oracle.javatools.parser.plsql.syntax.SqlDriver
SQLQueryException
- when there are errors in expression
public static void checkErrors(PlsqlRoot root, java.lang.String sql) throws SQLQueryException
root
- sql
