I am creating an SSIS Execute SQL Task that will use variables but it is giving me an error when I try to use it. When I try to run the below, it gives me an error and when I try to build the query, it gives me an error SQL Sytnax Errors encountered and unable to parse query. I am using an OLEDB connection. Am I not able to use variables to specify the tables?
You can't parameterize a table name.
Use the Expressions editor in your Execute SQL Task to Select a SqlStatementSource property.
Try "SELECT * FROM " + #[User::TableName]
After clicking OK twice (to exit the Task editor), you should be able to reopen the editor and find your table name in the SQL statement.
Add a string cast in a case where it might be a simple Object - (DT_WSTR,100)
You are using only single parameter(?) in the query and assigning 3 inputs to that parameters which is not fair put only single input and assign some variable as input as shown in image and change the value of variable respectively.
the parameter name should be incremented by 1 start with 0 because they are the indexes representing the "?" in the query which was written the query window.

I'm using a lookup stage as a source to fetch some data and i want to pass that output as the input to the next lookup stage. I tried adding #activity('Step1').output.firstRow.Col and it failed with scalar variable was not being declared. Also tried with #{activity('Step1').output.firstRow.col} which failed and the log shows only default expressions supported. Please help if it is possible.
I have accomplished this using dataflow, but considering the performance i would like to know if it can be done in a pipeline.
Please try this：
Query:select * from dbo.test5 where col = '#{activity('Lookup1').output.firstRow.col}'
Output:
Using snowflake connector I am trying to insert a record in a table.
In snowflake doc they have shown examples with hard coded strings, but when I try to use my variables instead, it doesn't work. Please suggest how to use variables in this case.
conn.cursor().execute(
"INSERT INTO cm.crawling_metrics(FEED_DATE,COMP_NAME,REFRESH_TYPE,CRAWL_INPUT,CRAWL_SUCCESS) VALUES " +
"(score_creation_date,compName,sRefreshType,mp_sku_count,comp_sku_count)"
I get the below error
snowflake.connector.errors.ProgrammingError: 000904 (42000): SQL compilation error: error line 1 at position 100
invalid identifier 'SCORE_CREATION_DATE'
NOTE: In the above code if i hard code with String instead of variables, it works.
Kindly suggest what is the right way ?
You need to use string interpolation / formatting for your code to use these as actual variables:
conn.cursor().execute(
"INSERT INTO cm.crawling_metrics (FEED_DATE, COMP_NAME, REFRESH_TYPE, CRAWL_INPUT, CRAWL_SUCCESS) VALUES " +
f"('{score_creation_date}', '{compName}', '{sRefreshType}', '{mp_sku_count}', '{comp_sku_count}')"
)
I am new to Python and I want to execute multiple SQL queries in one statement using python, but I am not able to find the appropriate way to do so.
I wrote following code but its throwing an error as " DatabaseError: ORA-00933: SQL command not properly ended."
import cx_Oracle;
SQLQuery = "select x from xyz where p= 'sn'; select * from abs where a ='qw';"
connection = cx_Oracle.connect('username', 'password', 'server')
cursor = connection.cursor()
cursor.execute(SQLQuery) #its throwing error here
It would be great if one can suggest me the appropriate function for executing the multiple queries in one call.
Appreciate your response. Thanks in advance.
What do you want to achieve with this?
Technically you could try to get rows from two tables or try to combine rows from different tables, but all this is directly done in SQL.
Remove ; (semicolon) at the end of query and it should run fine.
I am new to SQL stuff in blueprism, I am able to configure SQL object and execute simple queries, but I am facing trouble while trying to run multiline complex SQL queries.
when I was trying to execute the below query in blueprism, getting some error message, saying "Incorrect Syntax near Database2"
"select top 10 * from [Database1].[dbo].[Table1]
join [Database1].[dbo].[Table2] on [Database1].[dbo].[Table2].Fieldname1=[Database1].[dbo].[Table1].Fieldname2
join [Database2].[dbo].[Table1] on [Database2].[dbo].[Table1].Fieldname1=[Database1].[dbo].[Table2].Fieldname2"
Can somebody please help me, what was the wrong in the above query...
I found the answer myself, there should not be any additional white space characters in the query, entire query should be in continuous line. The beauty of blueprism is, it can execute any level of complex queries without any constraints, but need to modify the syntax accordingly. always we should mention the filename and table names in the following format - [databasename].[dbo].[tablename].[fieldname]
I am writing a shell script which involves BigQuery commands to query an existing table and save the results to a destination table.
However, since my script will be run periodically, I have a parameter for the date for which the query should run.
For example, my script looks like this:
DATE_FORMATTED=$(date +%Y%m%d)
bq query --destination_table=Desttables.abc_$DATE_FORMATTED "select hits_eventInfo_eventLabel from TABLE_DATE_RANGE([mydata.table_],TIMESTAMP($DATE_FORMATTED),TIMESTAMP($DATE_FORMATTED)) where customDimensions_index = 4"
I get the following error:
Error in query string: Error processing job 'pro-cn:bqjob_r5437894379_1': FROM clause with table wildcards matches no table
How else can I pass the variable $DATE_FORMATTED to the TABLE_DATE_RANGE function from BigQuery in order to help execute my query?
Use double quotes "" + single quote ''. For example, in your case:
TIMESTAMP("'$DATE_FORMATTED'")
OR
select "'$variable'" as dummy from your_table
You are probably missing the single quotes around the $DATE_FORMATTED value inside the TIMESTAMP functions. Without the quotes it's going to be defaulting to the EPOCH time.
Try with:
TIMESTAMP('$DATE_FORMATTED'),TIMESTAMP('$DATE_FORMATTED')
