Serde query understanding

–1 vote
In the following query:

CREATE TABLE my_table(a string, b string, ...) ROW FORMAT SERDE "org.apache.hadoop.hive.serde2.OpenCSVSerde" WITH SERDEPROPERTIES ( "separatorChar" = "\t", "quoteChar" = """, "escapeChar" = "\\" )

can you explain following things in above query?

"separatorChar" = "\t", "quoteChar" = """, "escapeChar" = "\\"

In the query mentioned in your question, the lines:

"separatorChar" = "\t",
"quoteChar" = """,
"escapeChar" = "\\"

are used to specify the field delimiters in your dataset. Sometimes there are different field delimiters in the dataset. So, to accept the data with different delimiters we can use these SerDe Properties.
