reads files containing SQL statements and extracts statements that match a given regular expression or that contain
|
|
USE \fIdb_name\fR

|
SET

|
statements\&. The utility was written for use with update log files (as used prior to MySQL 5\&.0) and as such expects statements to be terminated with semicolon (;) characters\&. It may be useful with other files that contain SQL statements as long as statements are terminated with semicolons\&.
