Imagine you have a primary composite index of last_name,first_name . Then you performed a search of WHERE first_name LIKE 'joh%' AND last_name LIKE 'smi%' . Does the wildcard used in the last_name condition mean that the first_name condition will not be used in further helping MySQL find indexes? In other words, by putting a wildcard on the last_name condition MySQL will only do a partial index lookup (and ignores conditions given in the columns that are to the right of last_name)? Further clarification of what I'm asking Example-1: Primary key is last_name, first_name . Example-2: Primary key

I have the query SELECT * FROM images WHERE tags LIKE '%example%hello%' I would like the database to select rows which have 'example' and 'hello' in the 'tags' column in any order, as in: A row with 'hello, test, example', also 'example, hello, test' or any other variation of this order. Is this possible, even without using LIKE? The rows must all contain everything specified with LIKE. EDIT: Such as, when I provide 'example' and 'hello' in the query, rows returned must contain both 'example' and 'hello'. You could try a simple OR for a quick solution: SELECT * FROM images WHERE tags LIKE '

I have a SQL Server table containing a nvarchar(max) column. I ran a query to select every row where this column contains the string 'remove'. Amongst the results, I have several rows where this column is populated with an empty string and I don't understand why these values have been returned. I tried to investigate further, on one of the empty string values returned. I found that the empty string value would match to certain LIKE conditions, but not others. For instance, it will match to '%remove%' and '%x%', but it won't match to '%q%'. Within the results grid on SQL Server Management

Is it possible to perform a request that checks the string representation of a Date instance. For example Restrictions.like("dateField", "%12%") to retrieve dates that either have String 12 in day or 12 in month or 12 in year where "dateField" is an instance of java.util.Date Thanks I had the same problem and here's what I did: First, I created my own Criterion implementation: public class DateLikeExpression implements Criterion { private static final long serialVersionUID = 1L; private String propertyName; private String value; public DateLikeExpression(String propertyName, String value) {

My code is something like this: $s = ociparse($conn, "SELECT u.email, u.city FROM tickets t, users u WHERE t.userId = u.userId AND u.city LIKE '%:city%'"); $city = $_GET['city']; oci_bind_by_name($s, ":city", $city); Apparently, it can't replace the ":city" The warning I get: Warning: oci_bind_by_name(): ORA-01036: illegal variable name/number in C:\xampp\htdocs\phpOracle\tickets.php on line 41 You need to bind it like this, you have to concatenate the % signs with it and you cannot have your bound variable wrapped in single quotes: $s = ociparse($conn, "SELECT u.email, u.city FROM tickets t,

I have the following sql prepared statement: SELECT * FROM video WHERE video_name LIKE ? Im using spring and jdbc. i have a method, where term is a searchterm, sjt is a SimpleJdbcTemplate, VideoMapper is a RowMapper and searchForTermQuery is the string from above ... return sjt.query(searchForTermQuery, new VideoMapper(), term); My table has 2 videos that match the term. However when I run the query none is found. I get an empty List. I tried playing with % around the question mark, but it only gave badGrammarExceptions. You need to put the % around the value itself, not around the placeholder
