Can you use variables as input and output when calling a stored procedure in COBOL?

Bunkyg — Tue, 21 Jun 2011 17:02:58 +0000

If you move data into your variable before calling your procedure, can the procedure then return a value back, which might be different? The procedure will intially be searching for the variable data, but, according to our .net programmer, will return a blank or null if it does not find the data. So far, that is not working, and he wants me to find the COBOL answer to this.

Would using a table variable from a function be efficient?

C1140 — Wed, 19 May 2010 07:16:49 +0000

We divided our tables from table zone_a, …_b, …_c to zone_z, these
tables have the same attributes. We have divided this tables in this way
so that any data that is under zone_a would only be on it’s specific
table, and the same with the other remaining table. Since per table
holds thousands of data per day we have decided it to be designed this
way and also hoping to reduce lock up of tables everytime a user
accesses the table.

Now, we made a function that returns a table. This function will handle
what table is to be selected. The body of this function contains a table
variable, it holds the data from the selected table. This function will
return the table variable

We have made this function hoping that it would be efficient to use for
other future procedures.

Is it efficient?

Thank You in advance.

dynamic temporary table variable usage

PaminBuckeyeLand — Thu, 25 Jun 2009 19:53:42 +0000

We have an sqr (running against a MS SQL Server DB), that references a dynamic temporary table variable in several begin-sql and begin-select statements. I am getting a syntax error in one begin-select statement where I can’t resolve the problem. It occurs after the INNER JOIN on the [$Temp_Final_IDlist] temp table. It appears as if SQR doesn’t see the replacement value for [$Temp_Final_IDlist].
I’ve already made sure that the variable is not empty.
Is there a limit in SQR on how many dynamic variables can be used in one program?

code:
Cursor #28:
SQL = SELECT SEV_21A.ID,
SEV_21A.HouseHoldKey,
SEV_21A.HouseHoldCombineFlag,
SEV_21A.OrderSeqNbrStd,
SEV_21A.PrefixRankAdjusted,
SEV_21A.SalutationPrefixCode,
SEV_21A.PrefixFormalSal,
SEV_21A.PrefixFormalSalPunc,
SEV_21A.NickName,
SEV_21A.FirstName,
SEV_21A.FirstNamePunc,
SEV_21A.LastName,
SEV_21A.Gender,

SEV_21B.ID,
SEV_21B.HouseHoldKey,
SEV_21B.HouseHoldCombineFlag,
SEV_21B.OrderSeqNbrStd,

SEV_21B.SalutationPrefixCode,
SEV_21B.PrefixFormalSal,
SEV_21B.PrefixFormalSalPunc,
SEV_21B.NickName,
SEV_21B.FirstName,
SEV_21B.FirstNamePunc,
SEV_21B.LastName,
SEV_21B.Gender

AND TFI_21A.DropIDFlag = ‘N’
INNER JOIN
Salutation_Elements_View SEV_21B ON SEV_21A.HouseHoldKey = SEV_21B.HouseHoldKey
AND SEV_21A.HouseHoldCombineFlag = SEV_21B.HouseHoldCombineFlag
AND SEV_21A.EntityType = SEV_21B.EntityType
AND SEV_21A.SalutationType = SEV_21B.SalutationType
AND SEV_21A.OrderSeqNbrStd <> SEV_21B.OrderSeqNbrStd
AND SEV_21B.LastName IS NOT NULL
AND SEV_21B.StopDateTime IS NULL
AND SEV_21B.StopUserID IS NULL

WHERE SEV_21A.LastName IS NOT NULL
AND SEV_21A.OrderSeqNbrStd = 1
AND SEV_21A.HouseHoldCombineFlag = ‘Y’
AND SEV_21A.SalutationType = ‘A’
AND SEV_21A.StopDateTime IS NULL
AND SEV_21A.StopUserID IS NULL

ORDER BY SEV_21A.HouseHoldKey, SEV_21A.ID

pass variable from Foreach loop to stored Procedure parameters

IG1944 — Wed, 18 Mar 2009 20:51:22 +0000

in control flow I run “Execute SQL Task” to retrive array variables like State Code (‘AR’, ‘WI’, .. et). Then I run ForeEach Loop Container and pass global variable gv_StateCode into Data Flow, where I run stored proc with one parameter in “OLE DB Source” (like exec sp_StProcname ?) and i assign parameter in Set Query parameters dialog to gv_StateCode as Parameter0 = User::gv_StateCode.
When I run this package I got error: “The SQL command requires a parameter named “@p_StateCode”, which is not found in the parameter mapping.”

Please help me to resolve this issue.

Thanks IG

SQL Server trigger , insert result of multiple where clause into a variable

Jacquesvdm — Tue, 11 Nov 2008 08:23:48 +0000

Hi All,

I have a select statement that stores the result in a variable,this works fine if there is only one condition and field in the clause.How do I go about it if there is more than one?

For example (Working one)
SELECT @Variable = (SELECT [Field] FROM [Table] WHERE [FIELD] = Value)

But I am looking for something like this

IF EXIST(SELECT * FROM [Table] WHERE [FIELD1] = Value1 AND [Field2] = Value2)
BEGIN
INSERT
@Variable
VALUE
[FIELD3]
END

Thanks Alot
