Problem Note 69398: Running DS2 code against long data types on SAS® Federation Server 4.4 with VARCHAR exceeding 1024 (Linux)/4096 (Windows) causes an access violation
 |  |  |  |  |
You might encounter an issue in which running DS2 code against long data types on SAS Federation Server 4.4 with a VARCHAR data type that exceeds 1,024 characters in Linux environments and 4,096 characters in Windows environments causes an access violation.
For example, you encounter the issue when you complete the following steps:
- Create a table using code similar to the following in Microsoft SQL Server database (assuming the DSN points to a database named "sas"):
proc sql;
connect to odbc (dsn="<MS SQL Server DSN>" user="<userid>" pw="<password>");
execute (
CREATE TABLE [dbo].[TestVCMID]
(
ID INT IDENTITY(1, 1) ,
TestData VARCHAR(MAX) ,
PRIMARY KEY CLUSTERED ( ID )
)
) by odbc;
execute (DECLARE @str1 VARCHAR(MAX) = 'a'
INSERT INTO [dbo].[TestVCMID]
( TestData )
SELECT REPLICATE(@str1, 8192)
) by odbc;
quit;
connect to odbc (dsn="<MS SQL Server DSN>" user="<userid>" pw="<password>");
execute (
CREATE TABLE [dbo].[TestVCMID]
(
ID INT IDENTITY(1, 1) ,
TestData VARCHAR(MAX) ,
PRIMARY KEY CLUSTERED ( ID )
)
) by odbc;
execute (DECLARE @str1 VARCHAR(MAX) = 'a'
INSERT INTO [dbo].[TestVCMID]
( TestData )
SELECT REPLICATE(@str1, 8192)
) by odbc;
quit;
- Run DS2 code similar to the following on SAS Federation Server 4.4 against a table similar to the one in step 1:
proc ds2 nolibs noprompt="driver=remts;server='<Federation Server host>';port=24141;
protocol=bridge;uid='<userid>';pwd='<password>';conopts=(driver=ds2;
conopts=(driver=sql;conopts=(DSN=DSFEDERATEDDSN)))";
protocol=bridge;uid='<userid>';pwd='<password>';conopts=(driver=ds2;
conopts=(driver=sql;conopts=(DSN=DSFEDERATEDDSN)))";
data null;
dcl int ID;
dcl varchar(10) value;
dcl int i;
dcl int rc;
dcl varchar(8192) TestData;
dcl int ID;
dcl package sqlstmt query('select ID, TestData from "sas"."dbo"."TestVCMID" where ID = ?', [value]);
method run();
this.value = 1;
rc = query.execute();
if (rc = 0) then do;
rc = query.bindResults([ID, TestData]);
rc = query.fetch();
put ID=;
put TestData=;
end;
end;
enddata;
run; quit;
dcl int ID;
dcl varchar(10) value;
dcl int i;
dcl int rc;
dcl varchar(8192) TestData;
dcl int ID;
dcl package sqlstmt query('select ID, TestData from "sas"."dbo"."TestVCMID" where ID = ?', [value]);
method run();
this.value = 1;
rc = query.execute();
if (rc = 0) then do;
rc = query.bindResults([ID, TestData]);
rc = query.fetch();
put ID=;
put TestData=;
end;
end;
enddata;
run; quit;
In this scenario, the following error message occurs:
ERROR: Access violation
The same issue occurs when you use a CLOB data type in Oracle.
The only workaround is to use a VARCHAR data type with a fixed length within the queried database table.
