Statements Property

In This Topic

Gets the collection of statements that make up the script.

Syntax

Visual Basic
C#

'Declaration
 
Public ReadOnly Property Statements As SqlStatementCollection

public SqlStatementCollection Statements {get;}

Property Value

Collection of statements.

Remarks

Use Statements to obtain SqlStatementCollection which allows to access individual statements of the script and execute them manually. The collection is read-only so you can not modify it in any way. It is also bound to originating DbScript object, which means that if you have altered ScriptText, previously obtained collection will be cleared.

Example

This sample shows how to retrieve collection of statements that make up the script and execute them one by one.

csharp

string script =
  "DROP TABLE DEPT;"+
  "CREATE TABLE DEPT ("+
  "  DEPTNO INT PRIMARY KEY,"+
  "  DNAME VARCHAR(14),"+
  "  LOC VARCHAR(13)"+
  ")WITH OIDS;"+
  "INSERT INTO DEPT VALUES (10,'ACCOUNTING','NEW YORK');"+
  "INSERT INTO DEPT VALUES (20,'RESEARCH','DALLAS');"+
  "INSERT INTO DEPT VALUES (30,'SALES','CHICAGO');"+
  "INSERT INTO DEPT VALUES (40,'OPERATIONS','BOSTON');"+
  "SELECT * FROM DEPT";
PgSqlConnection pgConn = new PgSqlConnection(
    "host=server;database=test;user id=postgres;");
PgSqlScript pgScript = new PgSqlScript(script,pgConn);
SqlStatementCollection pgColl = pgScript.Statements;
IDataReader pgReader;
pgConn.Open();
foreach (SqlStatement pgStatement in pgColl)
{
  Console.WriteLine(pgStatement.Text);
  try
  {
    pgReader = pgStatement.Execute();
    Console.WriteLine("  Records affected " + pgReader.RecordsAffected); 
    while (pgReader.Read()) 
    { 
      Console.WriteLine(pgReader.GetString(0)); 
    } 
    pgReader.Close(); 
    Console.WriteLine();
  }
  catch
  {
    Console.WriteLine("  Failed");
  }
}
pgConn.Close();

Visual Basic

Dim script As String = _
  "DROP TABLE DEPT;" + _
  "CREATE TABLE DEPT (" + _
  "  DEPTNO INT PRIMARY KEY," + _
  "  DNAME VARCHAR(14)," + _
  "  LOC VARCHAR(13)" + _
  ")WITH OIDS;" + _
    "INSERT INTO DEPT VALUES (10,'ACCOUNTING','NEW YORK');" + _
    "INSERT INTO DEPT VALUES (20,'RESEARCH','DALLAS');" + _
    "INSERT INTO DEPT VALUES (30,'SALES','CHICAGO');" + _
    "INSERT INTO DEPT VALUES (40,'OPERATIONS','BOSTON');" + _
    "SELECT * FROM DEPT"
Dim pgConn As PgSqlConnection = New PgSqlConnection( _
    "host=server;database=test;user id=postgres;")
Dim pgScript As PgSqlScript = New PgSqlScript(script, pgConn)
Dim pgColl As SqlStatementCollection = pgScript.Statements
Dim pgReader As IDataReader
pgConn.Open()
For Each pgStatement As SqlStatement In pgColl
  Console.WriteLine(pgStatement.Text)
  Try
    pgReader = pgStatement.Execute()
    Console.WriteLine("  Records affected " & pgReader.RecordsAffected)
    While pgReader.Read()
      Console.WriteLine(pgReader.GetString(0))
    End While
    pgReader.Close()
    Console.WriteLine()
  Catch ex As Exception
    Console.WriteLine("  Failed")
  End Try
Next pgStatement
pgConn.Close()
