which glob character matches zero or more characters?
0
standard sql uses a glob-like syntax for simple string matching in its codice_6 operator. the percent sign (%) matches zero or more characters, and the underscore matches exactly one character. the term "glob" is not generally used in the sql community, however. many implementations of sql have extended the codice_6 operator to allow a richer pattern-matching language incorporating elements of regular expressions.









































some proprietary extensions such as transact-sql provide the functionality, e.g., codice_8 and codice_9.
