Replacing all instances of data in one field with other data
Hi there --
I am running a MySQL 5.x server on a Fedora Core 8 system, and I have the following question:
What command can I use to replace all instances of one data entry in a field with a new one? For example, if I want to replace all instances the tape ID 12345 in the 'local' field with that of 678910 in the same 'local' field, what command would I use? Thanks.

Re: Replacing all instances of data in one field with other data
ALWAYS START WITH A BACKUP!!!
UPDATE [LOW_PRIORITY] [IGNORE] tbl_name
SET col_name1=expr1 [, col_name2=expr2 ...]
[WHERE where_definition]
[ORDER BY ...]
[LIMIT row_count]
So, that could be:
UPDATE TABLE_NAME
SET LOCAL=678910
WHERE LOCAL=12345
UPDATE [LOW_PRIORITY] [IGNORE] tbl_name
SET col_name1=expr1 [, col_name2=expr2 ...]
[WHERE where_definition]
[ORDER BY ...]
[LIMIT row_count]
So, that could be:
UPDATE TABLE_NAME
SET LOCAL=678910
WHERE LOCAL=12345
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?
