help with :ERROR: Expression using equals (=) has components that are of different data types.

Armand — Thu, 15 Jan 2015 18:16:35 GMT

Here is the code

proc sql;

create table work.test as

select a.Client_id, a.Client_name, a.Score, a.Status,

b.Client_id, b.Client_name, b.Score, b.Status,

(a.score-b.score) as Score_diff,

case when a.status=b.status then 'match' else 'no match' end as Status_test

from Client_Report2 a

left join Client_Report1 b on a.Client_id=b.Client_id;

quit;

The Status data type is mixed : numeric value, string,

Status field has :

>60

more than a year

when i run the code in bold i get this error: ERROR: Expression using equals (=) has components that are of different data types.

Any help, please?

You need the equal two sides to have compatible data type, you can use PUT to convert to character.

what do u mean by "equal two sides"?

thanks!

All of the = signs are where you are comparing variables from one table with variables from the other table.

For at least one of those the one table has the variable a numeric and the other has it as character.

It probably is best to find out why and fix the tables.

If you cannot do this then you can convert the numeric variable value to character string using put() function. For example put(a.status,1.). Or if the character values are valid numbers you can use the INPUT() function to convert them to a number. Example input(b.status,1.)

There are two places where your code uses an equal sign:

a.status=b.status

a.Client_id=b.Client_id

One of these has a "type mismatch". That means the variable you are processing is character in one incoming data set and numeric in the other incoming data set. Once you discover which variable is causing the problem, we can talk about solutions.

Good luck.

i did :

select put(a.status,1.), put(b.status,1.) or in the case when statement i get this error:

ERROR: Expression using equals (=) has components that are of different data types.

ERROR: Numeric format F in PUT function requires a numeric argument.

any idea?

thanks!

the variable Status is the one causing the problem because it has mixed values such as :

>60

more than a year

thanks!

Run a proc contents on both your data sets (Client_Report1, Client_Report2) and look at what types (numeric/character) are for the variable Status. Are they the same or different?

Re: help with :ERROR: Expression using equals (=) has components that are of different data types.

Armand — Thu, 15 Jan 2015 19:17:43 GMT

both reports show Status as CHAR.

Re: help with :ERROR: Expression using equals (=) has components that are of different data types.

Reeza — Thu, 15 Jan 2015 19:23:15 GMT

And Client_ID?

Re: help with :ERROR: Expression using equals (=) has components that are of different data types.

mohamed_zaki — Thu, 15 Jan 2015 19:28:47 GMT

from a.Client_Report2

left join b.Client_Report1 on a.Client_id=b.Client_id;

Is a and b refer to libref or you mean alias and your data set is in work ?

try

from Client_Report2 a

left join Client_Report1 b on (a.Client_id=b.Client_id);

Re: help with :ERROR: Expression using equals (=) has components that are of different data types.

Armand — Thu, 15 Jan 2015 19:31:31 GMT

it shows:

Client_id: Num

Client_name: CHAR

Score: Num

Status: CHAR

thanks!

Armand — Thu, 15 Jan 2015 19:34:19 GMT

sorry mistype

i did in my code as you mentioned above.

Re: help with :ERROR: Expression using equals (=) has components that are of different data types.

Astounding — Thu, 15 Jan 2015 19:34:37 GMT

Let me just confirm here. Are you saying all of these are true:

a.Client_ID is numeric

b.Client_ID is numeric

a.status is character

b.status is character

And you are still getting that error message?

Reeza — Thu, 15 Jan 2015 19:38:28 GMT

That's only one data set, what about the second data set. Can you post the actual proc contents output please? As well as the log that shows the error?

Re: help with :ERROR: Expression using equals (=) has components that are of different data types.

Armand — Thu, 15 Jan 2015 19:40:17 GMT

that s correct!

do you think the error has something to do with the fact that the same variable(Status) has mismatch type like this? :

>60

more than a year

Armand — Thu, 15 Jan 2015 19:52:16 GMT

the file u are requesting is huge. To simplify that s what proc content show:

Client_Report1:

TYPE LEN FORMAT INFORMAT LABEL

Client_id: Num 6 $6 $6 imdb id

Client_name: CHAR 68 $68 $68 Client name

Score: Num 8 Score

Status: CHAR 128 $128 $128 Status

Client_Report2

TYPE LEN FORMAT INFORMAT LABEL

Client_id: Num 6 $6 $6 imdb id

Client_name: CHAR 68 $68 $68 Client name

Score: Num 8 Score

Status: CHAR 128 $128 $128 Status

log:

ERROR: Expression using equals (=) has components that are of different data types.

You have

(a.score-b.scorre)

but the variable should be b.score in the original post. Was this retyped or actual copy?

Re: help with :ERROR: Expression using equals (=) has components that are of different data types.

Astounding — Thu, 15 Jan 2015 20:08:10 GMT

Armand,

Definitely not a result of a mix of:

>60

It's perfectly OK to store "50" as the value of a character field. The field is still character, no matter what characters it contains.

The one piece of your output that is decidedly weird is the PROC CONTENTS results for Client_ID. It is not possible to have a numeric variable with a format/informat of $6. Numeric formats/informats should not have a dollar sign.

Armand — Thu, 15 Jan 2015 20:35:25 GMT

typo error, it should be b.score
