![]() ![]() This provides a 'safer' search environment in web interfaces, since it prevents SQL injections. $dbh->selectrow_hashref($SQL_Stmnt, undef, 'Erik']}) Select * from tblUser where Name LIKE CONCAT('%', ? ,'%') It is possible to search wildchar patterns when using bind parameters. STRCMP(LOWER(name), LOWER('current_item_name')) The Fix I use for now, is to lowercase the strings in STRCMP(): SELECT id WHERE category = 1 AND STRCMP(name, 'current_item_name') = -1 ORDER BY name DESC LIMIT 1 Getting the Prev Item Button for display section: SELECT id WHERE category = 1 AND STRCMP(name, 'current_item_name') = 1 ORDER BY name LIMIT 1 Getting the Next Item Button for display section: SELECT id, name, price, description WHERE category = 1 ORDER BY name I have a section to display a single item from the list, then used the STRCMP to go to the next/prevoius item in the order it was displayed I have a table that I display, just a basic dump of the table order by a varchar field. Here is the what I was doing, and I hope this helps others. The LIKE operator is a logical operator that tests whether a string contains a specified pattern or not. In the manual it states "Before MySQL 4.0, STRCMP() is case sensitive.", I did not relize this, and I found out the hard way that STRCMP() is case-sensitive.Īlso I found it strange that STRCMP() is case-sensitive, but ORDER BY is case-insensitive. Swedish/Finnish string comparison rules are in User Comments Posted by Sascha René Leib on Octo1:29am This makes theĭefault comparison behavior case insensitive unless one or The second according to the current sort order, andĬharacter set when performing comparisons. SELECT COUNT(*) FROM foo WHERE bar NOT LIKE '%baz%' OR bar IS NULL ![]() The query SELECT COUNT(*) FROM foo WHERE bar LIKEĪssume that SELECT COUNT(*) FROM foo WHERE bar Mysql> SELECT filename, filename LIKE '%\\\\' FROM t1 Įxample, consider the following table and data: Mysql> SELECT filename, filename LIKE '%\\' FROM t1 ![]() The values using either of the following patterns: To test for values that end with backslash, you can match The end of the string, backslash stands for itself because When the pattern match is made, leaving a single backslashĮxception: At the end of the pattern string, backslash can The backslashes are stripped once by the parser and again In particular, trailing spaces are significant, which is notįollowing two wildcard characters in the pattern.īecause MySQL uses C escape syntax in strings (forĪ newline character), you must double any Mysql> SELECT 'ä' = 'ae' COLLATE latin1_german2_ci | 'ä' LIKE 'ae' COLLATE latin1_german2_ci | Mysql> SELECT 'ä' LIKE 'ae' COLLATE latin1_german2_ci Performs matching on a per-character basis, thus it can For example, itĬan be specified as a string expression or table column. The pattern need not be a literal string. Pattern matching using SQL simple regular expression ![]()
