sql-template

Motivation

Template string builder for SQL.

Key features

• tag based (easily extensible)
• made with love
• very simple
• drop in compatible with pg
• strongly tested with 100% code coverage

API/Usage

var SQL = require('sql-template');

pg(SQL`SELECT * FROM foo`)
  {text: 'SELECT * FROM foo', values: []} 

pg(SQL`SELECT * FROM foo WHERE age > ${22}`)
  {text: 'SELECT * FROM foo WHERE age > $1 ', values: [22]} 

Tags (transformers) list

$where$

pg(SQL`SELECT * FROM foo $where${ {name:'John doe'} }`)
  {text: 'SELECT * FROM foo WHERE "name" = $1 ', values: ["John doe"]} 

pg(SQL`SELECT * FROM foo $where${ {id: [1,2,3], type:'snow'} }`)
  {text: 'SELECT * FROM foo WHERE "id" IN($1,$2,$3) AND "type"=$4 ', values: [1,2,3,"snow"]} 

$set$

pg(SQL`UPDATE foo $set${ {joe: 22, bar: 'ok'} }`)
  {text: 'UPDATE foo SET "joe"=$1,"bar"=$2', values: [22, 'ok']}

$keys$

pg(SQL`INSERT INTO foo $keys${["joe", "bar"]} VALUES (${22}, ${'ok'})}`)
  {text: 'INSERT INTO foo ("joe", "bar") VALUES ($1,$2), values: [22, 'ok']}

$values$

pg(SQL`INSERT INTO foo (joe, bar) $values${ {joe: 22, bar: 'ok'} }`)
  {text: 'INSERT INTO foo (joe, bar) VALUES ($1,$2), values: [22, 'ok']}
  
const obj = {joe: 22, bar: 'ok'};
pg(SQL`INSERT INTO foo $keys${Object.keys(obj)} $values${obj}`)
  {text: 'INSERT INTO foo ("joe","bar") VALUES ($1,$2), values: [22, 'ok']}

or use the SQL.insert static api.

$id$

pg(SQL`SELECT * FROM $id${'foo'}`)
  {text: 'SELECT * FROM "foo"', values: []}

$in$

pg(SQL`SELECT * FROM foo WHERE id $in${[1,2,3]}`)
  {text: `SELECT * FROM foo WHERE id IN($1,$2,$3)', values: [1,2,3]}

Note that transformers internaly use ?: as parameter placeholder, per jsonb compliance.

Static API

SQL.insert

pq(SQL.insert('foo', {joe: 22, bar: 'ok'}))
  {text: 'INSERT INTO foo ("joe","bar") VALUES ($1,$2), values: [22, 'ok']}

SQL.search_blob (search_field, expression)

Compute a smart query expression.
