Functions ¶
func ApplyLimitOffset ¶
ApplyLimitOffset applies LIMIT and OFFSET operations to a DataFrame.
func CreateEmptyDataFrame ¶
CreateEmptyDataFrame creates an empty DataFrame with the same schema as the template.
func CreateTestDataFrame ¶
func CreateTestDataFrame(allocator memory.Allocator, config *TestDataFrameConfig) *dataframe.DataFrame
CreateTestDataFrame creates a standard test DataFrame with employee data. This consolidates the createTestDataFrame pattern found across multiple SQL test files.
func CreateTestDataFrameFromData ¶
func CreateTestDataFrameFromData(allocator memory.Allocator, data map[string]interface{}) *dataframe.DataFrame
CreateTestDataFrameFromData creates a DataFrame from custom test data.
func SafeInt64ToInt ¶
SafeInt64ToInt safely converts int64 to int with bounds checking.
Types ¶
type BaseTranslator ¶
type BaseTranslator struct {
// contains filtered or unexported fields
}
BaseTranslator provides common SQL translation functionality.
func NewBaseTranslator ¶
func NewBaseTranslator(allocator memory.Allocator) *BaseTranslator
NewBaseTranslator creates a new base translator with common functionality.
func (*BaseTranslator) ClearTables ¶
func (bt *BaseTranslator) ClearTables()
ClearTables removes all registered tables.
func (*BaseTranslator) GetAllocator ¶
func (bt *BaseTranslator) GetAllocator() memory.Allocator
GetAllocator returns the memory allocator.
func (*BaseTranslator) GetRegisteredTables ¶
func (bt *BaseTranslator) GetRegisteredTables() []string
GetRegisteredTables returns the list of registered table names.
func (*BaseTranslator) GetTable ¶
func (bt *BaseTranslator) GetTable(name string) (*dataframe.DataFrame, bool)
GetTable retrieves a registered table by name.
func (*BaseTranslator) HandleCommonErrors ¶
func (bt *BaseTranslator) HandleCommonErrors(operation string, err error) error
HandleCommonErrors provides standardized error handling for SQL operations.
func (*BaseTranslator) RegisterTable ¶
func (bt *BaseTranslator) RegisterTable(name string, df *dataframe.DataFrame)
RegisterTable registers a DataFrame with a table name.
func (*BaseTranslator) StandardizeColumns ¶
func (bt *BaseTranslator) StandardizeColumns(columns []string) []string
StandardizeColumns standardizes column names according to SQL conventions.
func (*BaseTranslator) ValidateTableExists ¶
func (bt *BaseTranslator) ValidateTableExists(tableName string) error
ValidateTableExists validates that a table is registered.
type TestDataFrameConfig ¶
type TestDataFrameConfig struct {
IncludeActive bool
RowCount int
CustomData map[string]interface{}
}
TestDataFrameConfig configures test DataFrame creation.
func DefaultTestDataFrameConfig ¶
func DefaultTestDataFrameConfig() *TestDataFrameConfig
DefaultTestDataFrameConfig returns default test DataFrame configuration.
