formats type names (dialect-specific) - -### Dialect Interface -Dialect-specific formatting is handled via the `Dialect` interface: -```go -type Dialect interface { - QuoteIdent(string) string - TypeName(ns, name string) string -

returns true if list has items -- `todo(node) Node` - placeholder for unimplemented conversions (returns nil) - -## Common Node Types - -### Statements -- `SelectStmt` - SELECT queries with FromClause, WhereClause, etc. -- `InsertStmt` - INSERT with Relation, Cols, SelectStmt, OnConflictClause -- `UpdateStmt` - UPDATE with Relations, TargetList, WhereClause -- `DeleteStmt` - DELETE with Relations, FromClause (for JOINs), Targets - -### Expressions -- `A_Expr` - General expression with operator (e.g., `a + b`, `@param`) -- `ColumnRef` - Column reference with Fields list -- `FuncCall` - Function call with Func, Args, aggregation options -- `TypeCast` - Type cast with Arg and TypeName -- `ParenExpr` - Parenthesized expression -- `VariableExpr` - MySQL user variable (e.g., `@user_id`) - -### Table References -- `RangeVar` - Table reference with schema, name, alias -- `JoinExpr` - JOIN with Larg, Rarg, Jointype, Quals/UsingClause - -## MySQL-Specific Nodes - -- `VariableExpr` - User variables (`@var`), distinct from sqlc's `@param` syntax -- `IntervalExpr` - INTERVAL expressions -- `OnDuplicateKeyUpdate` - MySQL's ON DUPLICATE KEY UPDATE clause -- `ParenExpr` - Explicit parentheses (TiDB parser wraps expressions) - -## Important Distinctions - -### MySQL @variable vs sqlc @param -- MySQL user variables (`@user_id`) use `VariableExpr` - preserved as-is in output -- sqlc named parameters (`@param`) use `A_Expr` with `@` operator - replaced with `?` -- The `named.IsParamSign()` function checks for `A_Expr` with `@` operator - -### Type Modifiers -- `TypeName.Typmods` holds type modifiers like `varchar(255)` -- For MySQL, only populate Typmods for types where length is user-specified: -
