Public Attributes
std::string	schemaName
	The schema name of the table to update.

std::string	tableName
	The name of the table to update.

std::vector< std::pair< std::string, SqlVariant > >	setColumns
	The columns and their values to set.

std::vector< std::pair< std::string, std::string > >	setExpressions
	Column-to-expression assignments that cannot be represented as a literal value.

std::string	whereColumn
	The column name for the WHERE clause.

std::string	whereOp
	The comparison operator for the WHERE clause (e.g., "=", "<>", etc.).

SqlVariant	whereValue
	The value for the WHERE clause.

std::string	whereExpression
	Pre-rendered WHERE-clause body (the text after `WHERE`), used when the condition cannot be expressed with the simple `(whereColumn op whereValue)` triple — e.g. composite `AND`/`OR`/`NOT`, `IS NULL`, `IN (subquery)`, or `EXISTS (subquery)`. When non-empty, this takes precedence over the structured triple at SQL-emission time.

Member Data Documentation

◆ schemaName

std::string Lightweight::SqlUpdateDataPlan::schemaName

The schema name of the table to update.

Definition at line 444 of file MigrationPlan.hpp.

◆ tableName

std::string Lightweight::SqlUpdateDataPlan::tableName

The name of the table to update.

Definition at line 447 of file MigrationPlan.hpp.

◆ setColumns

std::vector<std::pair<std::string, SqlVariant> > Lightweight::SqlUpdateDataPlan::setColumns

The columns and their values to set.

Definition at line 450 of file MigrationPlan.hpp.

◆ setExpressions

std::vector<std::pair<std::string, std::string> > Lightweight::SqlUpdateDataPlan::setExpressions

Column-to-expression assignments that cannot be represented as a literal value.

Each entry is (column name, raw SQL expression). The expression is emitted verbatim after "col" = at SQL-rendering time — used for things like set TARGET = SOURCE or set CTR = CTR + 1 where the RHS references another column or contains arithmetic. Entries here are appended to the SET clause after setColumns.

Definition at line 458 of file MigrationPlan.hpp.

◆ whereColumn

std::string Lightweight::SqlUpdateDataPlan::whereColumn

The column name for the WHERE clause.

Definition at line 461 of file MigrationPlan.hpp.

◆ whereOp

std::string Lightweight::SqlUpdateDataPlan::whereOp

The comparison operator for the WHERE clause (e.g., "=", "<>", etc.).

Definition at line 464 of file MigrationPlan.hpp.

◆ whereValue

SqlVariant Lightweight::SqlUpdateDataPlan::whereValue

The value for the WHERE clause.

Definition at line 467 of file MigrationPlan.hpp.

◆ whereExpression

std::string Lightweight::SqlUpdateDataPlan::whereExpression

Pre-rendered WHERE-clause body (the text after WHERE), used when the condition cannot be expressed with the simple (whereColumn op whereValue) triple — e.g. composite AND/OR/NOT, IS NULL, IN (subquery), or EXISTS (subquery). When non-empty, this takes precedence over the structured triple at SQL-emission time.
