In This Topic
    Statements Property
    In This Topic
    Gets the collection of statements that make up the script.
    Syntax
    '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.
    string script =
      @"if object_id('dept', 'U') is not null
      drop table dept;
    CREATE TABLE Dept(
      DEPTNO int PRIMARY KEY NOT NULL,
      DNAME varchar(14) NULL,
      LOC varchar(13) NULL
    );"+
      "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";
    SqlConnection myConn = new SqlConnection(
        "User Id=sa;Server=localhost;Initial Catalog=Test;");
    SqlScript myScript = new SqlScript(script,myConn);
    SqlStatementCollection myColl = myScript.Statements;
    IDataReader myReader;
    myConn.Open();
    foreach (SqlStatement myStatement in myColl)
    {
