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')

Say I have an InfluxDB query where the user supplies a measurement. In this case the user supplies the value "foo". Then I would construct the query:
SELECT * from "foo"
WHERE time > "2022-06-21T18:27:16.041Z"
What's the best way to prevent injection attacks here? I know InfluxDB supports bind parameters, but apparently that feature only works for the WHERE clause, so it wouldn't help me.
I was thinking of trying this:
const query = `
SELECT "value" FROM "${Influx.escape.measurement(key)}"
WHERE time > "2022-06-21T18:27:16.041Z"
`
...but based on my testing that function doesn't escape quotation marks, only spaces.
I'm using InfluxDB 1.x in Node.js via the influx npm package.
Before sending the value to the query try filtering chars like single and double quotes
Looking into docs, articles I can see that every subquery is in brackets, like:
select * from (select "value" from "measurement") <where_caluse>
So filtering for brackets beetwen "FROM" and "WHERE" should be enough.

I want to store the value of the sqlite statement in a variable
backup=$(sqlite3 "/home/miguel/Desktop/SO/ProjetoFinal/Backup_Principal.db" "SELECT periocidade_backup FROM STORAGE WHERE path'$path';")
But when i echo $backup it returns the following:
sqlite3 "/home/miguel/Desktop/SO/ProjetoFinal/Backup_Principal.db" "SELECT periocidade_backup FROM STORAGE WHERE path='$path';"
What am I doing wrong?
the part of your code '$path' is using a single quote which is literal and show exactly as what is in the quotes, which would not use the variable's value. using speech marks like the following should work, "'$path'"
I am calling HQL from shell script.
I am passing variable to HQL from querying from other table. Variable I am passing as follows:
$$A1=('123','124')
I see variable $$A1 properly in shell script with echo statement and it displayed as ('123','124').
but when I am using this variable in query, its missing single quotes. I mean it is passing as (123,124)
I am passing as $$A1 as follows:
select * from table1 where cd in $$A1
query is taking as select * from table where cd in (123,124)
why single quotes are missing when it is passing to the query.
appreciate any help on this.
Thanks,
Babu
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.
In Sybase SQL, I would like to execute a String containing SQL.
I would expect something like this to work
declare #exec_str char(100)
select #exec_str = "select 1"
execute #exec_str
go
from the documentation of the exec command
execute | exec
is used to execute a stored procedure or an extended stored
procedure (ESP). This keyword is
necessary if there are multiple
statements in the batch.
execute is also used to execute a string containing Transact-SQL.
However my above example gives an error. Am I doing something wrong?
You need bracketing:
execute ( #exec_str )
