tsvsql

Templates TSV values into a SQL template

input.tsv: apple 1 banana 2

tsvsql $ < input.tsv dist/build/tsvsql/tsvsql 'INSERT into fruits (name, price) VALUES ($1, $2:num);' INSERT into fruits (name, price) VALUES ('apple', 1); INSERT into fruits (name, price) VALUES ('banana', 2);

WARNING: Use single quotes around the SQL template expression so that Bash does not do interpolation.

'null' text is translated into NULL:

input2.tsv apple 1 banana null

tsvsql $ < input2.tsv dist/build/tsvsql/tsvsql 'INSERT into fruits (name, price) VALUES ($1, $2:num);' INSERT into fruits (name, price) VALUES ('apple', 1); INSERT into fruits (name, price) VALUES ('banana', NULL);

The subtitution placeholders are like this:

$1      # value is a string; the value is quoted and escaped
$2:num  # value is a number; not quoted
$3:bool # value is a bool; "t" is true, "f" is false

The placeholders start counting the first TSV value from position 1, not zero.
