CASE WHEN... AND in SQL ERROR

PI_Science

I'm working in MYSQL and trying to write a CASE WHEN Statement with multiple AND X<Y conditions. When it is finished, the statement below will be much longer with 15 more AND conditions, but right now this shorter version won't verify. The purpose of this statement is simply to find the lowest value across 15 columns for each row. Thoughts on what is going wrong (or perhaps a simplier way to find the minimum?? (The "min" function only finds the lowest value out of all the rows in the column (and not out of all the columns in a row, whic is what I'm trying to find). Thanks!

 

SELECT
CASE WHEN `Venturer_Dist`< `Strategist_Dist` AND `Venturer_Dist`< `Operator_Dist`
THEN 'Venturer'
END
FROM transform_data_3

Ok,

 

Try:

 

SELECT
CASE WHEN `Venturer_Dist`< `Strategist_Dist` AND `Venturer_Dist`< `Operator_Dist`
THEN 'Venturer' END  AS ColumnName
FROM transform_data_3

If you are using this is a dataflow try also to loose the "`" :

 

SELECT
CASE WHEN Venturer_Dist < Strategist_Dist  AND  Venturer_Dist <  Operator_Dist
THEN 'Venturer'  END  AS ColumnName
FROM transform_data_3

 

Let me know how it goes.

Hi,

 

What's the error?

 

Can/did you run transform_data_3 correctly?

Hi Ricardo,

 

This is the error message:

 

 The database reported a syntax error. Incorrect column name 'CASE WHEN `Venturer_Dist`< `Strategist_Dist` AND `Venturer_Dist`< `Operator_Dist` THEN 'Venturer' E'

 

transform_data_3 is running smoothly!

 

Thanks,
