Mysql query search a string in all columns of a table - mysql

Question

I wonder how I can mount a SQL as portable as possible to query for all columns of a table for a specific phrase, like:
Table
ID | Name | text | Date | Author | Status
1 | Augusto Weiand | Test text | 2010-01-01 | Deividi | 1
Query
SELECT *
FROM table
WHERE columns LIKE '%augusto%2010%text%"
I did not put enough detail, excuse me, I like to make a dynamic SQL, where I do not need to specify the columns with 'AND' or 'OR', as it is possible to do in Postgres:
Select *
From table
Where table::text ~~ '%augusto%2010%text%'

Answer 1

Here is how you would concatenate the values in dynamic SQL:
set #Pattern = '%augusto%';
select #q := concat('select * from Table1 ',
'where concat(', group_concat(column_name), ', "") like "', #Pattern, '"'
)
from information_schema.columns c
where table_name = 'Table1';
prepare st from #q;
execute st;
deallocate prepare st;
Of course, dynamic SQL is not particularly portable. The idea would work in most databases. The code would look different.
Tested and working here.
And finally, you can do this with variable substitution (which is the better approach):
select #q := concat('select * from Table1 ',
'where concat(', group_concat(column_name), ', "") like ?'
)
from information_schema.columns c
where table_name = 'Table1';
set #p = '%augusto%';
prepare st from #q;
execute st using #p;
deallocate prepare st;
Also tested (;-).

Answer 2

It's doable, although I strongly suggest you look into full-text search for efficiency;
To avoid looking for all patterns in all fields one by one, you can just concat and search in that;
SELECT *
FROM (SELECT id,CONCAT(name,'|',text,'|',date,'|',author,'|',status) txt
FROM Table1) a
WHERE txt LIKE '%augusto%'
AND txt LIKE '%2010%'
AND txt LIKE '%text%';
Note that no indexing will help you here, since you're searching in a calculated column. On the other hand, since you're searching with a leading wildcard %searchterm, you won't get much help from indexes even if searching field by field :)
An SQLfiddle to test with.

Answer 3

try this
Select * FROM table WHERE text LIKE "%text%"
OR date LIKE "%2010%"
OR Name LIKE "%augusto%"
if you want them all together then use AND
Select * FROM table WHERE text LIKE "%text%"
AND date LIKE "%2010%"
AND Name LIKE "%augusto%"

Answer 4

you can use this store procedure to search a text in all column in table
CREATE PROCEDURE dbo.sp_FindStringInTable #stringToFind VARCHAR(100),
#schema
sysname, #table sysname
AS
BEGIN TRY
DECLARE #sqlCommand varchar(max) = 'SELECT * FROM [' + #schema + '].[' +
#table + '] WHERE '
SELECT #sqlCommand = #sqlCommand + '[' + COLUMN_NAME + '] LIKE ''' +
#stringToFind + ''' OR '
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = #schema
AND TABLE_NAME = #table
AND DATA_TYPE IN ('char','nchar','ntext','nvarchar','text','varchar')
SET #sqlCommand = left(#sqlCommand,len(#sqlCommand)-3)
EXEC (#sqlCommand)
PRINT #sqlCommand
END TRY
BEGIN CATCH
PRINT 'There was an error. Check to make sure object exists.'
PRINT error_message()
END CATCH
Execute it like this
EXEC sp_FindStringInTable '%searchword%','schema_name', 'tablename'
