I have mysql table that has a column that stores xml as a string. I need to find all tuples where the xml column contains a given string of 6 characters. Nothing else matters--all I need to know is if this 6 character string is there or not.
So it probably doesn't matter that the text is formatted as xml.
Question: how can I search within mysql?
ie
SELECT * FROM items WHERE items.xml [contains the text '123456']
Is there a way I can use the LIKE operator to do this?
Using like might take longer time so use full_text_search:
SELECT * FROM items WHERE MATCH(items.xml) AGAINST ('your_search_word')
When you are using the wordpress prepare line, the above solutions do not work. This is the solution I used:
$Table_Name = $wpdb->prefix.'tablename';
$SearchField = '%'. $YourVariable . '%';
$sql_query = $wpdb->prepare("SELECT * FROM $Table_Name WHERE ColumnName LIKE %s", $SearchField) ;
$rows = $wpdb->get_results($sql_query, ARRAY_A);
you mean:
SELECT * FROM items WHERE items.xml LIKE '%123456%'
Why not use LIKE?
SELECT * FROM items WHERE items.xml LIKE '%123456%'
SELECT * FROM items WHERE `items.xml` LIKE '%123456%'
The %
operator in LIKE
means "anything can be here".
