Constants ¶
const ( DialectPostgreSQL = "postgresql" DialectMySQL = "mysql" DialectSQLite = "sqlite" )
Dialect names a supported target database. It is the single generation-time value carrying every engine difference, so a target is chosen once instead of per facet.
Variables ¶
var SupportedDialects = []string{DialectPostgreSQL, DialectMySQL, DialectSQLite}
SupportedDialects lists every accepted Dialect value, in the order error messages report them.
Functions ¶
func Generate ¶
func Generate(filename string, source []byte, options GenerateOptions) ([]byte, error)
Generate parses, validates, and compiles a SQL template module to Go.
func ValidateDialect ¶ added in v0.2.2
ValidateDialect reports whether name selects a supported database. It is exported so a caller discovering SQL templates can reject a missing or unknown dialect as a configuration error, before generating anything.
Types ¶
type BinaryExpr ¶
type BinaryExpr = syntax.BinaryExpr
type CompileError ¶
func (*CompileError) Error ¶
func (e *CompileError) Error() string
type ConditionalExpr ¶
type ConditionalExpr = syntax.ConditionalExpr
type Declaration ¶
type Declaration = syntax.Declaration
type ExecutorResolver ¶ added in v0.1.6
ExecutorResolver identifies a package function with the signature func(context.Context) (SQLExecutor, error).
type ExpressionNode ¶
type ExpressionNode = syntax.ExpressionNode
type ExternalDecl ¶
type ExternalDecl = syntax.ExternalDecl
type GenerateOptions ¶
type GenerateOptions struct {
Package string
// Dialect selects the target database. It is required: there is no implicit
// default, because a silently assumed dialect emits placeholders the target
// engine rejects.
Dialect string
// ContextAPI adds <Component>Context wrappers which resolve an executor
// from context.Context while preserving the explicit executor APIs.
ContextAPI bool
// ContextOnly publishes the Context-resolved function under the declared
// component name and makes the executor-taking function unexported. It
// implies ContextAPI and generates no <Component>Context wrapper.
ContextOnly bool
// ExecutorResolver selects a framework-specific Context resolver. A nil
// resolver uses sqlbind.SQLExecutorFromContext. Setting it implies ContextAPI.
ExecutorResolver *ExecutorResolver
}
GenerateOptions controls SQL code generation.
type IdentifierExpr ¶
type IdentifierExpr = syntax.IdentifierExpr
type LiteralExpr ¶
type LiteralExpr = syntax.LiteralExpr
type MemberExpr ¶
type MemberExpr = syntax.MemberExpr
type ParseError ¶
type ParseError = syntax.ParseError
type RelationNode ¶
type RelationNode struct {
Kind string `json:"kind"`
Pos Position `json:"pos"`
Name string `json:"name"`
Arguments []Expr `json:"arguments,omitempty"`
Alias string `json:"alias"`
}
RelationNode is a structurally embedded private sql.relation<T> statement. It is emitted into the caller's builder, so placeholders remain globally ordered after runtime conditions are resolved.
func (*RelationNode) NodeType ¶
func (n *RelationNode) NodeType() string
type TemplateDecl ¶
type TemplateDecl = syntax.TemplateDecl
