|

| +** schema. This is because each database connection requires its own unique
|
| +** instance of the sqlite3_vtab* handle used to access the virtual table
|
| +** implementation. sqlite3_vtab* handles can not be shared between
|
| +** database connections, even when the rest of the in-memory database
|
| +** schema is shared, as the implementation often stores the database
|
| +** connection handle passed to it via the xConnect() or xCreate() method
|
| +** during initialization internally. This database connection handle may
|
| +** then be used by the virtual table implementation to access real tables
|
| +** within the database. So that they appear as part of the callers
|
| +** transaction, these accesses need to be made via the same database
|
| +** connection as that used to execute SQL operations on the virtual table.
|
| +**
|
| +** All VTable objects that correspond to a single table in a shared
|
| +** database schema are initially stored in a linked-list pointed to by
|
| +** the Table.pVTable member variable of the corresponding Table object.
|
| +** When an sqlite3_prepare() operation is required to access the virtual
|
| +** table, it searches the list for the VTable that corresponds to the
|
| +** database connection doing the preparing so as to use the correct
|
| +** sqlite3_vtab* handle in the compiled query.
|
| +**
|
| +** When an in-memory Table object is deleted (for example when the
|
| +** schema is being reloaded for some reason), the VTable objects are not
|
| +** deleted and the sqlite3_vtab* handles are not xDisconnect()ed
|
| +** immediately. Instead, they are moved from the Table.pVTable list to
|
| +** another linked list headed by the sqlite3.pDisconnect member of the
|
| +** corresponding sqlite3 structure. They are then deleted/xDisconnected
|
| +** next time a statement is prepared using said sqlite3*. This is done
|
| +** to avoid deadlock issues involving multiple sqlite3.mutex mutexes.
|
| +** Refer to comments above function sqlite3VtabUnlockList() for an
|
| +** explanation as to why it is safe to add an entry to an sqlite3.pDisconnect
|
| +** list without holding the corresponding sqlite3.mutex mutex.
|
| +**

| +** Each node of an expression in the parse tree is an instance
|
| +** of this structure.
|
| +**
|
| +** Expr.op is the opcode. The integer parser token codes are reused
|
| +** as opcodes here. For example, the parser defines TK_GE to be an integer
|
| +** code representing the ">=" operator. This same integer code is reused
|
| +** to represent the greater-than-or-equal-to operator in the expression
|
| +** tree.
|
| +**
|
| +** If the expression is an SQL literal (TK_INTEGER, TK_FLOAT, TK_BLOB,
|
| +** or TK_STRING), then Expr.token contains the text of the SQL literal. If
|
| +** the expression is a variable (TK_VARIABLE), then Expr.token contains the
|
| +** variable name. Finally, if the expression is an SQL function (TK_FUNCTION),
|
| +** then Expr.token contains the name of the function.
|
| +**
|
| +** Expr.pRight and Expr.pLeft are the left and right subexpressions of a
|
| +** binary operator. Either or both may be NULL.
|
| +**
|
| +** Expr.x.pList is a list of arguments if the expression is an SQL function,
|
| +** a CASE expression or an IN expression of the form "<lhs> IN (<y>, <z>...)".
|
| +** Expr.x.pSelect is used if the expression is a sub-select or an expression of
|
| +** the form "<lhs> IN (SELECT ...)". If the EP_xIsSelect bit is set in the
|
| +** Expr.flags mask, then Expr.x.pSelect is valid. Otherwise, Expr.x.pList is
|
| +** valid.
|
| +**
|
| +** An expression of the form ID or ID.ID refers to a column in a table.
|
| +** For such expressions, Expr.op is set to TK_COLUMN and Expr.iTable is
|
| +** the integer cursor number of a VDBE cursor pointing to that table and
|
| +** Expr.iColumn is the column number for the specific column. If the
|
| +** expression is used as a result in an aggregate SELECT, then the
|
| +** value is also stored in the Expr.iAgg column in the aggregate so that
|
| +** it can be accessed after all aggregates are computed.
|
| +**
|
| +** If the expression is an unbound variable marker (a question mark
|
| +** character '?' in the original SQL) then the Expr.iTable holds the index
|
| +** number for that variable.
|
| +**
|
| +** If the expression is a subquery then Expr.iColumn holds an integer
|
| +** register number containing the result of the subquery. If the
|
| +** subquery gives a constant result, then iTable is -1. If the subquery
|
| +** gives a different answer at different times during statement processing
|
| +** then iTable is the address of a subroutine that computes the subquery.
|
| +**
|
| +** If the Expr is of type OP_Column, and the table it is selecting from
|
| +** is a disk table or the "old.*" pseudo-table, then pTab points to the
|
| +** corresponding table definition.
|
| +**
|
| +** ALLOCATION NOTES:
|
| +**
|
| +** Expr objects can use a lot of memory space in database schema. To
|
| +** help reduce memory requirements, sometimes an Expr object will be
|
| +** truncated. And to reduce the number of memory allocations, sometimes
|
| +** two or more Expr objects will be stored in a single memory allocation,
|
| +** together with Expr.zToken strings.
|
| +**
|
| +** If the EP_Reduced and EP_TokenOnly flags are set when
|
| +** an Expr object is truncated. When EP_Reduced is set, then all
|
| +** the child Expr objects in the Expr.pLeft and Expr.pRight subtrees
|
| +** are contained within the same memory allocation. Note, however, that
|
| +** the subtrees in Expr.x.pList or Expr.x.pSelect are always separately
|
| +** allocated, regardless of whether or not EP_Reduced is set.

|

|
| +**
|
| +** SRT_Except Remove results from the temporary index pDest->iSDParm.
|
| +**
|
| +** SRT_Exists Store a 1 in memory cell pDest->iSDParm if the result
|
| +** set is not empty.
|
| +**
|
| +** SRT_Discard Throw the results away. This is used by SELECT
|
| +** statements within triggers whose only purpose is
|
| +** the side-effects of functions.
|
| +**
|
| +** All of the above are free to ignore their ORDER BY clause. Those that
|
| +** follow must honor the ORDER BY clause.
|
| +**
|
| +** SRT_Output Generate a row of output (using the OP_ResultRow
|
| +** opcode) for each row in the result set.
|
| +**
|
| +** SRT_Mem Only valid if the result is a single column.
|
| +** Store the first column of the first result row
|
| +** in register pDest->iSDParm then abandon the rest
|
| +** of the query. This destination implies "LIMIT 1".
|

|

|
| +** row of result as the key in table pDest->iSDParm.
|
| +** Apply the affinity pDest->affSdst before storing
|
| +** results. Used to implement "IN (SELECT ...)".
|
| +**
|
| +** SRT_EphemTab Create an temporary table pDest->iSDParm and store
|
| +** the result there. The cursor is left open after
|
| +** returning. This is like SRT_Table except that
|
| +** this destination uses OP_OpenEphemeral to create
|
| +** the table first.
|
| +**
|

|
| +** results each time it is invoked. The entry point
|
| +** of the co-routine is stored in register pDest->iSDParm
|
| +** and the result row is stored in pDest->nDest registers
|
| +** starting with pDest->iSdst.
|
| +**
|
| +** SRT_Table Store results in temporary table pDest->iSDParm.
|
| +** SRT_Fifo This is like SRT_EphemTab except that the table
|
| +** is assumed to already be open. SRT_Fifo has
|
| +** the additional property of being able to ignore
|
| +** the ORDER BY clause.
|

|
| +** But also use temporary table pDest->iSDParm+1 as
|
| +** a record of all prior results and ignore any duplicate
|
| +** rows. Name means: "Distinct Fifo".

|
| +** an index). Append a sequence number so that all entries
|
| +** are distinct.
|
| +**
|
| +** SRT_DistQueue Store results in priority queue pDest->iSDParm only if
