![]() Use this escape sequence in your SQL statements or the corresponding escape sequence in your programming language of choice to insert line breaks as needed. In conclusion, inserting line breaks in PostgreSQL when updating a text field is simple using the ‘\n’ escape sequence. This Python code uses the psycopg2 library to connect to a PostgreSQL database, create a cursor, execute an SQL statement to update a text field with two lines of text separated by the ‘\n’ escape sequence, commit the changes, and close the connection. For example, in Python, you can use the ‘\n’ escape sequence like this: import psycopg2Ĭonn = nnect(database="mydb", user="myuser", password="mypassword", host="localhost", port="5432")Ĭur.execute("UPDATE table_name SET field_name = 'This is the first line.\nThis is the second line.' WHERE id = 1 ") If you are using a programming language to interact with your PostgreSQL database, you can also use the appropriate escape sequence for a newline character in that language. The text being inserted contains two lines, separated by the ‘\n’ escape sequence. In this example, we are updating the ‘field_name’ column of the row with an ‘id’ of 1 in the ‘table_name’ table. SET field_name = 'This is the first line.\nThis is the second line.' Here is an example of how to do this: UPDATE table_name postgres \d t Table 'public.t' Column Type Modifiers -+-+- s text postgres SELECT s, md5 ( s ), replace ( replace ( replace ( s, E' ', ' ' ), E'\t', '\t' ), E'\r', '\r' ) FROM t s md5 replace. This can be done using the escape sequence for a newline character, ‘\n’. You can find details here, here and here. When updating a text field in PostgreSQL, it is common to need to insert line breaks in the data. The backslash has no special meaning in SQL, so ' ' is a backslash followed by the character n. As a result, the cell will look like this: First line Second line To use 'escape sequences' in a string literal you need to use an 'extended' constant.
