SQL::ConnectionToString Method

Syntax

String as C = ToString(SQLStatement as C [, Arguments as SQL::Arguments][, RowsToCopy = -1 as N [, StartRow = 1 as N [, ColumnSeparator as C [,RowSeparator as C [, ColumnReferences as SQL::TableInfo [, UserContext as P]]]]]])

ArgumentsSQL::Arguments: A SQL::Arguments object. One or more arguments to be resolved when the SELECT statement is executed.
RowsToCopyNumeric: Default = -1 (all). The number of rows to copy.

RowSeparatorCharacter: Default = CR-LF. Characters to insert between rows.
ColumnReferencesSQL::TableInfo: A SQL::TableInfo object. When data is formatted for a column in the result set: (1) if ReferenceColumns has a column with a matching name, that object will be used to format the data; (2) otherwise the ColumnInfo property of the result set is used to format the data.

Discussion

The ToString() method fetches data to a string using a SQL query.

Example

dim conn as SQL::Connection
dim connString as C
dim query as C
query = "select firstname, lastname from customer where lastname > 'm'"
connString = "{A5API='Access', FileName='c:\program files\a5v8\mdbfiles\alphasports.mdb'}"
if .not. conn.open(connString)
    ui_msg_box("Error", conn.CallResult.text)
    end
end if
ui_msg_box("Results", conn.ToString(query))
conn.close()

This example retrieves four rows of data, starting at the third row. Note : Even though there are no arguments to pass, the following script DIMs and passes the args variable.

dim conn as SQL::Connection
dim connString as C
dim query as C
dim args as SQL::Arguments
query = "select firstname, lastname from customer where lastname > 'm'"
connString = "{A5API='Access', FileName='c:\program files\a5v8\mdbfiles\alphasports.mdb'}"
if .not. conn.open(connString)
    ui_msg_box("Error", conn.CallResult.text)
    end
end if
ui_msg_box("Results", conn.ToString(query, args, 4, 3, "|", crlf()))
conn.close()
