Statement Class

A Statement object is used for executing SQL statements. The statement may be a query returning result set, or a non-query statement returning an update count. Non-query SQL can be insert, update, or delete statements. Non-query SQL statements can also be DML statements (such as create, grant, and so on) or stored procedure calls.

A query, insert / update / delete, or stored procedure call statements may have IN bind parameters, while a stored procedure call statement may have either OUT bind parameters or bind parameters that are both IN and OUT, referred to as IN/OUT parameters.

The Statement class methods are divided into three categories:

Table 13-42 Enumerated Values used by the Statement Class

Attribute Options
Status
  • NEEDS_STREAM_DATA indicates that output Streams must be written for the streamed IN bind parameters. If there is more than one streamed parameter, call the getCurrentStreamParam() method to find out the bind parameter needing the stream. If the statement is executed iteratively, call getCurrentIteration() to find the iteration for which stream needs to be written.

  • PREPARED indicates that the Statement is set to a query.

  • RESULT_SET_AVAILABLE indicates that the getResultSet() method must be called to get the result set.

  • STREAM_DATA_AVAILABLE indicates that the input Streams must be read for the streamed OUT bind parameters. If there is more than one streamed parameter, call the getCurrentStreamParam() method to find out the bind parameter needing the stream. If the statement is executed iteratively, call getCurrentIteration() to find the iteration for which stream needs to be read.

  • UPREPARED indicates that the Statement object is not set to a query.

  • UPDATE_COUNT_AVAILABLE indicates that the getUpdateCount() method must be called to find out the update count.

setDataBuffer()

Specifies a data buffer where data would be available. Also used for OUT bind parameters of callable statements.

The buffer parameter is a pointer to a user allocated data buffer. The current length of data must be specified in the length parameter. The amount of data should not exceed the size parameter. Finally, type is the data type of the data.

Note that not all types can be supplied in the buffer. For example, all OCCI allocated types (such as Bytes, Date and so on) cannot be provided by the setDataBuffer() interface. Similarly, C++ Standard Library strings cannot be provided with the setDataBuffer() interface either. The type can be any of OCI data types such VARCHAR2, CSTRING, CHARZ and so on.

If setDataBuffer() is used to specify data for iterative or array executes, it should be called only once in the first iteration only. For subsequent iterations, OCCI would assume that data is at buffer +(i*size) location where i is the iteration number. Similarly the length of the data would be assumed to be at (length+i).

Syntax

void setDataBuffer(

buffer
Pointer to user-allocated buffer. For iterative or array executes, it should have numIterations() size bytes in it. For array fetches, it should have numRows * size bytes in it. For gather or scatter binds and defines, this structure stores the address of OCIIOVec and the number of OCIIOVec elements that start at that address.
type
Type of the data that is provided (or retrieved) in the buffer.
size
Size of the data buffer; for iterative and array executes, it is the size of each element of the data items. For gather or scatter binds and defines, it is the size of the OCIIOVecArray to which the buffer points; the mode must be set to IOVEC.
length
Pointer to the length of data in the buffer; for iterative and array executes, it should be an array of length data for each buffer element; the size of the array should be equal to arrayLength().
ind
Indicator. For iterative and array executes, an indicator for every buffer element.
rc
Returns code; for iterative and array executes, a return code for every buffer element.
 


setDataBufferArray()

Sets the maximum number of invocations that will be made for the DML statement. This must be called before any parameters are set on the prepared statement. The larger the iterations, the larger the numbers of parameters sent to the server in one round trip. However, a large number causes more memory to be reserved for all the parameters. Note that this is just the maximum limit. Actual number of iterations depends on the number of calls to addIteration().

Syntax

Parameter Description

It can be used to truncate the LONG column by reading or writing it into a string or Bytes data type.

If the getSQL() or setBytes() method has been called to bind a value to an IN/OUT parameter of a PL/SQL procedure, and the size of the OUT value is expected to be greater than the size of the IN value, then setMaxParamSize() should be called.

   vector<Ref<T>> &vect,
   string &sqltype);
Available only on platforms where partial ordering of function templates is supported. setVectorOfRefs() can be used instead.

Parameter Description
stmt
Statement on which parameter is to be set.
paramIndex
Parameter index; first parameter is 1, second is 2, and so on.
vect
The vector to be set.
sqltype
Sqltype of the collection in the database. For example, CREATE TYPE num_coll AS VARRAY OF NUMBER. And the column/parameter type is num_coll. The sqltype would be num_coll.
schemaName
Name of the schema used
typeName
Type


setVectorOfRefs()

Sets a parameter to a vector; should be used when the type is a collection of REFs or nested tables of REFs.

Syntax Description
template  <class T> void setVectorOfRefs(
   Statement *stmt, unsigned int paramIndex,
   const vector<Ref<T> > &vect,
   const string &sqltype);
Sets a parameter to a vector; should be used when the type is a collection of REFs are varrays or nested tables of REFs.
template  <class T>  void setVectorOfRefs(
   Statement *stmt,
   unsigned int paramIndex,
   const vector<Ref<T> > &vect,
   const string &sqltype);
Used for multibyte support.
template  <class T> void setVectorOfRefs(
   Statement *stmt,
   unsigned int paramIndex,
   const vector<Ref<T>> &vect,
   const string &schemaName,
   const string &typeName);
Used for multibyte support.
template  <class T> void setVectorOfRefs(
   Statement *stmt,
   unsigned int paramIndex,
   const vector<Ref<T> &vect,
   const UString &schemaName,
   const UString &typeName);
Used for UTF16 support on platforms where partial ordering of function templates is not supported, such as Windows NT and z/OS.
template <class T>  void setVector(
Statement *stmt,
unsigned int paramIndex,
const vector<T* > &vect,
const UString &schemaName,
const UString &typeName);
Used for UTF16 support on platforms where partial ordering of function templates is supported.

Parameter Description
stmt
Statement on which parameter is to be set.
paramIndex
Parameter index; first parameter is 1, second is 2, and so on.
vect
Vector to be set.
sqltype
Sqltype of the parameter or column. Use setVectorOfRefs() instead of specialized function setVector() for Ref<T>.
schemaName
Name of the schema used
typeName
Type


status()

Returns the current status of the statement. Useful when there is streamed data to be written (or read). Other methods such as getCurrentStreamParam() and getCurrentIteration() can be called to find out the streamed parameter that needs to be written and the current iteration number for an iterative or array execute. The status()method can be called repeatedly to find out the status of the execution.

The returned value, Status, is defined in Table 13-42.

Syntax

Status status() const;
