Dump a MSSQL query into a TSV / JSON file.
Download the binary, specify a connection string as an environment variable (MSSQL_CONN)
and run it specifying the query you wanna run (-q):
export MSSQL_CONN="sqlserver://sa:Password123\!@127.0.0.1:1433"
./mssqldump -q "SELECT Name, 1 as ID, RAND() as thing from sys.Databases"
master 1 0.4318099474883688
tempdb 1 0.4318099474883688
model 1 0.4318099474883688
msdb 1 0.4318099474883688
test 1 0.4318099474883688
If you want to include column names in the output, use the -c option:
./mssqldump -q "SELECT Name, 1 as ID, RAND() as thing from sys.Databases" -c
Name ID thing
master 1 0.23937146273025442
tempdb 1 0.23937146273025442
model 1 0.23937146273025442
msdb 1 0.23937146273025442
test 1 0.23937146273025442
It also supports output in newline delimited JSON -- BigQuery anyone?
./mssqldump -q "SELECT Name, 1 as ID, RAND() as thing from sys.Databases" -f json
{"ID":1,"Name":"master","thing":0.6214426254735921}
{"ID":1,"Name":"tempdb","thing":0.6214426254735921}
{"ID":1,"Name":"model","thing":0.6214426254735921}
{"ID":1,"Name":"msdb","thing":0.6214426254735921}
{"ID":1,"Name":"test","thing":0.6214426254735921}
If your query is v, mssqldump will print out its version information:
./mssqldump -qv
