SQL stored procedure does not work

ChatterBox

Hi,

I've tried creating a procedure to spread revenue over 13 periods using MySQL as follows. Error's thrown at declaration/ setting variables. 

 

drop procedure if exists load_foo_test_data;

delimiter $$
create procedure load_foo_test_data()
BEGIN

Set @v_max = 13;
Set @v_counter =1;

start transaction;
while `v_counter` < `v_max` do
insert into bla bla bla....
set `v_counter`= `v_counter`+1;
end while;
commit;
end; $$

delimiter ;

call load_foo_test_data();

 

Please advice me on this .. thanks

In Domo each transform can only run a single command. You have, by my count, 5 commands trying to run and it will throw an error.

 

So here is your script, but I've marked each line that Domo will consider to be an individual command:

* drop procedure if exists load_foo_test_data;
* delimiter $$
* create procedure load_foo_test_data()
BEGIN
Set @v_max = 13;
Set @v_counter =1;
start transaction;
while `v_counter` < `v_max` do
insert into bla bla bla....
set `v_counter`= `v_counter`+1;
end while;
commit;
end; $$
* delimiter ;
* call load_foo_test_data();

I think you'll need to do three seperate transforms in Domo.

 

Transform 1:
DROP PROCEDURE IF EXISTS load_foo_test_data;

 

Transform 2:
CREATE PROCEDURE load_foo_test_data()
BEGIN
Set @v_max = 13;
Set @v_counter =1;
start transaction;
while `v_counter` < `v_max` do
insert into bla bla bla....
set `v_counter`= `v_counter`+1;
end while;
commit;
end;

 

Transform 3:
CALL load_foo_test_data();

 

Note: Once you've run the second transform, you cannot run it again unless you run the first one (to drop the procedure).

Thank you. This helped me get to the next step in solving the problem ?

My stored procedure is not working, how should I break this up?

Declare @SearchStr nvarchar(100)

SET  @SearchStr='Search String' BEGIN

CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

SET NOCOUNT ON

DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128),
@SearchStr2 nvarchar(110)  SET  @TableName = ''    SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

WHILE @TableName IS NOT NULL    
BEGIN       
  SET @ColumnName = ''      
  SET @TableName =  (
    SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' +    QUOTENAME(TABLE_NAME)) FROM INFORMATION_SCHEMA.TABLES 
    WHERE    TABLE_TYPE = 'BASE TABLE'
    AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
    AND OBJECTPROPERTY(      OBJECT_ID(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)),
        'IsMSShipped') = 0)

  WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)      
  BEGIN
    SET @ColumnName = (
      SELECT MIN(QUOTENAME(COLUMN_NAME))
      FROM INFORMATION_SCHEMA.COLUMNS
      WHERE TABLE_SCHEMA = PARSENAME(@TableName, 2)
        AND TABLE_NAME = PARSENAME(@TableName, 1)
      AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar')
      AND QUOTENAME(COLUMN_NAME) > @ColumnName)
      IF @ColumnName IS NOT NULL            
      BEGIN
      INSERT INTO #Results
      EXEC
      (
        'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + 
          ', 3630) FROM ' + @TableName + ' (NOLOCK) ' +
        ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
      )             
      END       
    END     
  END

  SELECT ColumnName, ColumnValue FROM #Results END
