In the above example, you will get records of not matching with Brazil (BRA), the United States of America (USA), and Canada(CAN). How to use multiple NOT LIKE conditions select country_cde, date, name, age In the above example, I did filter records of matching with either Brazil (BRA), the United States of America (USA), and Canada(CAN). select column1, column2, column3įrom my_table Real-life example with multiple Like conditionsīelow example is to get records from TRAVEL-DET table (travel details table). select column1, column2, column3įrom my_table How to give Multiple Like Conditionsīelow example says, general syntax of usage of multiple like conditions in Where clause. Without formally scripting a Stored Procedure, this is as good as it is going to get.Below is the simple SQL to give Like condition in Where clause. The SELECT will let you see the generated SQL WHERE table_schema=DATABASE() AND table_name='foo' AND column_name IN Here is the Dynamic SQL to generate the same query USE mydbĬONCAT('SELECT ',column_name,' AS name FROM ',table_name) For this example, let's suppose the following If the intent is to select some columns and generate a single column list of the distinct values, then Dynamic SQL is needed to produce such a query. This would produce a distinct list of names. Nothing could be more elegant that using UNION SELECT her_name AS name FROM foo In this instance, what makes UNION an absolute must is the merging of three columns into a single column. : Calculating values from three related tables, without using join or union.Others have submitted answers trying aggregation to collect data without using UNION Where one of the dictionary views: SELECT Why does this like query does not work I need the fields with either sports or pub or both SELECT FROM table WHERE interests LIKE. (SELECT := 0) r, INFORMATION_SCHEMA.COLUMNS t Using a constant expression: select 1 line Using an auxiliary table: create table aux(line int) Of course there are different ways to create a table containing the three rows with values 1,2,3: Pivot Query: select elt(aux.line,foo.his_name,foo.her_name,foo.other_name) all_name Insert into foo(his_name,her_name,other_name) values ('four','five','six') Insert into foo(his_name,her_name,other_name) values ('one','two','three') MySQL 5.6 Schema Setup: create table foo ( multiple rows as a single row, MySQL can only execute the query if it can. 8 I have a table with several columns which I want to SELECT: SELECT hisname, hername, othername FROM foo Bu, I instead I want to combine the results all into a single column. Instead the ELT function one can use IF or CASE. The IN operator can work like an comparison between a number of values. Each query row can be filled by the appropriate data. If we want to rename multiple column names, we might use the below syntax: ALTER TABLE tablename CHANGE oldcolumnname1 newcolumnname1 Data Type. Now we have three rows in our query for each row in the base table foo. We want to create 3 rows for each row of the foo table, so we create an auxiliary table containing three rowsĪnd (cross) join it to the foo table. So MySQL does not have such an "elegant" way to unpivot a table.Ī way to do such unpivoting without the use of UNION can be done buy using a join. So if table_references equals foo the query cannot contains more rows than the table foo. But I do not want to use text as a comparison factor. Neither the WHERE, GROUP BY, HAVING, LIMIT, SELECT, INTO, FOR UPDATE nor the LOCK IN SHARE MODE clause can increase the number of rows defined by the FROM clause. I want to do a 'select' in MySQL using the operator 'LIKE'. This is the syntax diagram of the select statement Oracle you can use the following statement to make columns to rows It is unclear to me what is a "more elegant way".
