close
public void close() throws SQLServerExceptionReleases any resources associated with the file reader.- Specified by:
closein interfaceAutoCloseable- Throws:
SQLServerException- when an error occurs

getRowData
public Object[] getRowData() throws SQLServerException
Description copied from interface:ISQLServerBulkDataReturns the data for the current row as an array of Objects. Each Object must match the Java language Type that is used to represent the indicated JDBC data type for the given column. For more information, see 'Understanding the JDBC Driver Data Types' for the appropriate mappings.- Specified by:
getRowDatain interfaceISQLServerBulkData- Returns:
- The data for the row.
- Throws:
SQLServerException- If there are any errors in obtaining the data.
-
next
public boolean next() throws SQLServerExceptionDescription copied from interface:ISQLServerBulkDataAdvances to the next data row.- Specified by:
nextin interfaceISQLServerBulkData- Returns:
- True if rows are available; false if there are no more rows
- Throws:

-
isEscapeColumnDelimitersCSV
public boolean isEscapeColumnDelimitersCSV()
Returns whether the rules to escape delimiters are used.- Returns:
- true if the rules are used, false otherwise.
-
setEscapeColumnDelimitersCSV
public void setEscapeColumnDelimitersCSV(boolean escapeDelimiters)
When set to true, the following rules will be used to parse CSV files: Each field may or may not be enclosed in double quotes. If fields are not enclosed with double quotes, then double quotes may not appear inside the fields. Fields containing double quotes, and delimiters should be enclosed in double quotes. If double-quotes are used to enclose fields, then a double-quote appearing inside a field must be escaped by preceding it with another double quote. Spaces are considered part of a field. Spaces before and after enclosing double quotes are ignored.- Parameters:
escapeDelimiters- true if the rules above to be used.
