sqlparser Build Status Coverage Report card GoDoc

Go package for parsing MySQL SQL queries.

Notice

The backbone of this repo is extracted from vitessio/vitess.

Inside vitessio/vitess there is a very nicely written sql parser. However as it's not a self-contained application, I created this one. It applies the same LICENSE as vitessio/vitess.

Usage

import (
    "github.com/smlxl/sqlparser"
)

Then use:

sql := "SELECT * FROM table WHERE a = 'abc'"
stmt, err := sqlparser.Parse(sql)
if err != nil {
	// Do something with the err
}

// Otherwise do something with stmt
switch stmt := stmt.(type) {
case *sqlparser.Select:
	_ = stmt
case *sqlparser.Insert:
}

Alternative to read many queries from a io.Reader:

r := strings.NewReader("INSERT INTO table1 VALUES (1, 'a'); INSERT INTO table2 VALUES (3, 4);")

tokens := sqlparser.NewTokenizer(r)
for {
	stmt, err := sqlparser.ParseNext(tokens)
	if err == io.EOF {
		break
	}
	// Do something with stmt or err.
}

See parse_test.go for more examples, or read the godoc.

func FormatImpossibleQuery ¶ 

func FormatImpossibleQuery(buf *TrackedBuffer, node SQLNode)

FormatImpossibleQuery creates an impossible query in a TrackedBuffer. An impossible query is a modified version of a query where all selects have where clauses that are impossible for mysql to resolve. This is used in the vtgate and vttablet:

- In the vtgate it's used for joins: if the first query returns no result, then vtgate uses the impossible query just to fetch field info from vttablet - In the vttablet, it's just an optimization: the field info is fetched once form MySQL, cached and reused for subsequent queries

func GetBindvars ¶ 

func GetBindvars(stmt Statement) map[string]struct{}

GetBindvars returns a map of the bind vars referenced in the statement.

func GetPriorityFromStatement ¶ 

func GetPriorityFromStatement(statement Statement) (string, error)

func Normalize ¶ 

func Normalize(stmt Statement, reserved *ReservedVars, bindVars map[string]*querypb.BindVariable) error

Normalize changes the statement to use bind values, and updates the bind vars to those values. The supplied prefix is used to generate the bind var names. The function ensures that there are no collisions with existing bind vars. Within Select constructs, bind vars are deduped. This allows us to identify vindex equality. Otherwise, every value is treated as distinct.

func ParseAndBind ¶ 

func ParseAndBind(in string, binds ...*querypb.BindVariable) (query string, err error)

ParseAndBind is a one step sweep that binds variables to an input query, in order of placeholders. It is useful when one doesn't have any parser-variables, just bind variables. Example:

type CountStar ¶ 

type CountStar struct {

	// TL;DR; This makes sure that reference equality checks works as expected
	//
	// You're correct that this might seem a bit strange at first glance.
	// It's a quirk of Go's handling of empty structs. In Go, two instances of an empty struct are considered
	// identical, which can be problematic when using these as keys in maps.
	// They would be treated as the same key and potentially lead to incorrect map behavior.
	//
	// Here's a brief example:
	//
	// “`golang
	// func TestWeirdGo(t *testing.T) {
	// 	type CountStar struct{}
	//
	// 	cs1 := &CountStar{}
	// 	cs2 := &CountStar{}
	//  if cs1 == cs2 {
	// 	  panic("what the what!?")
	//  }
	// }
	// “`
	//
	// In the above code, cs1 and cs2, despite being distinct variables, would be treated as the same object.
	//
	// The solution we employed was to add a dummy field `_ bool` to the otherwise empty struct `CountStar`.
	// This ensures that each instance of `CountStar` is treated as a separate object,
	// even in the context of out semantic state which uses these objects as map keys.
	OverClause *OverClause
	// contains filtered or unexported fields

) SQLNode

CopyOnRewrite traverses a syntax tree recursively, starting with root, and calling pre and post for each node as described below. Rewrite returns a syntax tree, where some nodes can be shared with the original syntax tree.

If pre is not nil, it is called for each node before the node's children are traversed (pre-order). If pre returns false, no children are traversed, but post is still called for that node.

If post is not nil, and a prior call of pre didn't return false, post is called for each node after its children are traversed (post-order).

In the post call, the cursor can be used to abort the current traversal altogether.

Also in the post call, a user can replace the current node. When a node is replaced, all the ancestors of the node are cloned, so that the original syntax tree remains untouched

The `cloned` function will be called for all nodes that are cloned or replaced, to give the user a chance to copy any metadata that needs copying.

Only fields that refer to AST nodes are considered children; i.e., fields of basic types (strings, []byte, etc.) are ignored.

If post is not nil, and a prior call of pre didn't return false, post is called for each node after its children are traversed (post-order). If post returns false, traversal is terminated and Apply returns immediately.

Only fields that refer to AST nodes are considered children; i.e., fields of basic types (strings, []byte, etc.) are ignored.
