+# Dolphin Engine (MySQL) - Claude Code Guide
+
+The dolphin engine handles MySQL parsing and AST conversion using the Marino parser
+(a sqlc-maintained fork of the TiDB / pingcap parser).
+
+## Architecture
+
+### Parser Flow
+```
+SQL String → Marino Parser → Marino AST → sqlc AST → Analysis/Codegen
+```
+
+### Key Files
+- `convert.go` - Converts Marino AST nodes to sqlc AST nodes
+- `format.go` - MySQL-specific formatting (identifiers, types, parameters)
+- `parse.go` - Entry point for parsing MySQL SQL
+
+## Marino Parser
+
+The Marino parser (`github.com/sqlc-dev/marino`) is used for MySQL parsing. It is a
+hard fork of `github.com/pingcap/tidb/pkg/parser` with a flatter package layout
+(no `pkg/parser/...` prefix) and the former `test_driver` types merged into the
+`ast` package as `ValueExprBase` / `ParamMarkerExprBase`.
+
+```go
+import (
+    pcast "github.com/sqlc-dev/marino/ast"
+    "github.com/sqlc-dev/marino/mysql"
+    "github.com/sqlc-dev/marino/types"
+)
+```
+
+### Common Marino Types
+- `pcast.SelectStmt`, `pcast.InsertStmt`, etc. - Statement types
+- `pcast.ColumnNameExpr` - Column reference
+- `pcast.FuncCallExpr` - Function call
+- `pcast.BinaryOperationExpr` - Binary expression
+- `pcast.VariableExpr` - MySQL user variable (@var)
+- `pcast.Join` - JOIN clause with Left, Right, On, Using
+
+## Conversion Pattern
+
+Each TiDB node type has a corresponding converter method:
+
+```go
+func (c *cc) convertSelectStmt(n *pcast.SelectStmt) *ast.SelectStmt {
+    return &ast.SelectStmt{
+        FromClause:  c.convertTableRefsClause(n.From),
+        WhereClause: c.convert(n.Where),
+        // ...
+    }
+}
+```
+
+The main `convert()` method dispatches to specific converters:
+```go
+func (c *cc) convert(node pcast.Node) ast.Node {
+    switch n := node.(type) {
+    case *pcast.SelectStmt:
+        return c.convertSelectStmt(n)
+    case *pcast.InsertStmt:
+        return c.convertInsertStmt(n)
+    // ...
+    }
+}
+```
+
+## Key Conversions
+
+### Column References
+```go
+func (c *cc) convertColumnNameExpr(n *pcast.ColumnNameExpr) *ast.ColumnRef {
+    var items []ast.Node
+    if schema := n.Name.Schema.String(); schema != "" {
+        items = append(items, NewIdentifier(schema))
+    }
+    if table := n.Name.Table.String(); table != "" {
+        items = append(items, NewIdentifier(table))
+    }
+    items = append(items, NewIdentifier(n.Name.Name.String()))
+    return &ast.ColumnRef{Fields: &ast.List{Items: items}}
+}
+```
+
+### JOINs
+```go
+func (c *cc) convertJoin(n *pcast.Join) *ast.List {
+    if n.Right != nil && n.Left != nil {
+        return &ast.List{
+            Items: []ast.Node{&ast.JoinExpr{
+                Jointype:    ast.JoinType(n.Tp),
+                Larg:        c.convert(n.Left),
+                Rarg:        c.convert(n.Right),
+                Quals:       c.convert(n.On),
+                UsingClause: convertUsing(n.Using),
+            }},
+        }
+    }
+    // No join - just return tables
+    // ...
+}
+```
+
+### MySQL User Variables
+MySQL user variables (`@var`) are different from sqlc's `@param` syntax:
+```go
+func (c *cc) convertVariableExpr(n *pcast.VariableExpr) ast.Node {
+    // Use VariableExpr to preserve as-is (NOT A_Expr which would be treated as sqlc param)
+    return &ast.VariableExpr{
+        Name:     n.Name,
+        Location: n.OriginTextPosition(),
+    }
+}
+```
+
+### Type Casts (CAST AS)
+```go
+func (c *cc) convertFuncCastExpr(n *pcast.FuncCastExpr) ast.Node {
+    typeName := types.TypeStr(n.Tp.GetType())
+    // Handle UNSIGNED/SIGNED specially
+    if typeName == "bigint" {
+        if mysql.HasUnsignedFlag(n.Tp.GetFlag()) {
+            typeName = "bigint unsigned"
+        } else {
+            typeName = "bigint signed"
+        }
+    }
+    return &ast.TypeCast{
+        Arg:      c.convert(n.Expr),
+        TypeName: &ast.TypeName{Name: typeName},
+    }
+}
+```
+
+### Column Definitions
+```go
+func convertColumnDef(def *pcast.ColumnDef) *ast.ColumnDef {
+    typeName := &ast.TypeName{Name: types.TypeToStr(def.Tp.GetType(), def.Tp.GetCharset())}
+
+    // Only add Typmods for types where length is meaningful
+    tp := def.Tp.GetType()
+    flen := def.Tp.GetFlen()
+    switch tp {
+    case mysql.TypeVarchar, mysql.TypeString, mysql.TypeVarString:
+        if flen >= 0 {
+            typeName.Typmods = &ast.List{
+                Items: []ast.Node{&ast.Integer{Ival: int64(flen)}},
+            }
+        }
+    // Don't add for DATETIME, TIMESTAMP - internal flen is not user-specified
+    }
+    // ...
+}
+```
+
+### Multi-Table DELETE
+MySQL supports `DELETE t1, t2 FROM t1 JOIN t2 ...`:
+```go
+func (c *cc) convertDeleteStmt(n *pcast.DeleteStmt) *ast.DeleteStmt {
+    if n.IsMultiTable && n.Tables != nil {
+        // Convert targets (t1.*, t2.*)
+        targets := &ast.List{}
+        for _, table := range n.Tables.Tables {
+            // Build ColumnRef for each target
+        }
+        stmt.Targets = targets
+
+        // Preserve JOINs in FromClause
+        stmt.FromClause = c.convertTableRefsClause(n.TableRefs).Items[0]
+    } else {
+        // Single-table DELETE
+        stmt.Relations = c.convertTableRefsClause(n.TableRefs)
+    }
+}
+```
+
+## MySQL-Specific Formatting
+
+### format.go
+```go
+func (p *Parser) TypeName(ns, name string) string {
+    switch name {
+    case "bigint unsigned":
+        return "UNSIGNED"
+    case "bigint signed":
+        return "SIGNED"
+    }
+    return name
+}
+
+func (p *Parser) Param(n int) string {
+    return "?"  // MySQL uses ? for all parameters
+}
+```
+
+## Common Issues and Solutions
+
+### Issue: Panic in Walk/Apply
+**Cause**: New AST node type not handled in `astutils/walk.go` or `astutils/rewrite.go`
+**Solution**: Add case for the node type in both files
+
+### Issue: MySQL @variable being treated as parameter
+**Cause**: The preprocessor's dialect said `@name` is sqlc syntax
+**Solution**: MySQL sets `AtSign: false` in `internal/sql/preprocess/dialect.go`, so
+`@user_id` is left alone before the parser ever sees it
+
+### Issue: Type length appearing incorrectly (e.g., datetime(39))
+**Cause**: Using internal `flen` for all types
+**Solution**: Only populate `Typmods` for types where length is user-specified (varchar, char, etc.)
+
+## Testing
+
+### TestFormat
+Tests that SQL can be:
+1. Parsed
+2. Formatted back to SQL
+3. Re-parsed
+4. Re-formatted to match
+
+### TestReplay
+Tests the full sqlc pipeline:
+1. Parse schema and queries
+2. Analyze
+3. Generate code
+4. Compare with expected output
