SELECT column_name 中的 MySQL Like 语句

Question

I am trying to select the column names from a specific table, where the table name is like '98673'

So I am using this:

SELECT 
    column_name
FROM 
    information_schema.columns
WHERE 
    table_name='lime_survey_98673'
    AND column_name LIKE '98673'

However this will not result in any data. Though I do have column names with '98673Blah' in there.

I know I must be doing something wrong, but what??

Answer 1

For the LIKE you have to add a wildcard %, so:

SELECT 
    column_name
FROM 
    information_schema.columns
WHERE 
    table_name='lime_survey_98673'
    AND column_name LIKE '98673%'

Answer 2

USE %

SELECT column_name
FROM information_schema.columns
WHERE table_name='lime_survey_98673'
AND column_name LIKE '%98673%'

% indicates a wildcard and returns any column_name that contains 98673

Answer 3

Try it without the part AND column_name LIKE '98673' unless you really need it or:

SELECT column_name
FROM information_schema.columns
WHERE table_name LIKE '%lime_survey_98673%'
-- AND column_name LIKE '%98673%'  // only if needed

For more information take a look at the documentation for:

• LIKE operator

• STRCMP() function

Answer 4

You need to add %

SELECT 
    column_name
FROM 
    information_schema.columns
WHERE 
    table_name='lime_survey_98673'
    AND column_name LIKE '%98673%'

this means that column_name contains 98673 .

Answer 5

也可以这样做：

show columns from lime_survey_98673 like '%98673%';

Answer 6

I think you need to add wildcard with table name also.

SELECT 
    column_name,
    table_name
FROM 
    information_schema.columns
WHERE
    schema_name = 'db_name' 
    AND table_name='%98673%'
    AND column_name LIKE '%98673%'

In this way you can get columns name list all tables and there columns name contain the text like '98673' from specific database or schema.
