How can I export a mySQL #temp table to a .csv file within script?

Question

I'd like to write a script that allows me to export .csv files from 15-20 temporary tables I created, using a script instead of having to copy and paste in a separate .csv file and then save them down.

:!!sqlcmd -S server -d database-E -Q "SET NOCOUNT ON 
SELECT * FROM TABLE" -o "C:\Users\name\Documents\folder\filename.csv"
-W -w 1024 -s ","

I've tried this, which works (not formatting correctly) but it doesn't seem to be work at all for a temp table; the .csv file contains this.

Msg 208  Level 16    State 1     Server SERVERNAME
Invalid object name '#TEMPTABLE'.       

I cannot obtain "elevated privileges" to be able to use BCP export, because I cannot write a stored procedure, create a new database, or access the command line. Is there a workaround for this?

Temp tables are ephemeral; they do not persist across sessions. Instead of creating temp tables, create actual tables, either in the database that you're working with, or in tempdb , then export the data from tempdb

An example:

sqlcmd -S server -d database -E -Q "If Exists (select * FROM tempdb.sys.tables WHERE name = 'Tmp_DataExport1') drop TABLE tempdb..Tmp_DataExport1;"

sqlcmd -S server -d database -E -Q "SELECT TOP 5 * INTO tempdb..Tmp_DataExport1 FROM T_SourceTable"

sqlcmd -S server -d database -E -Q "SELECT * FROM tempdb..Tmp_DataExport1" -o "c:\\temp\\filename.csv" -W -w 1024 -s ","
