フォーマットできないケース

ケース1

INSERT INTO sample_table
(col1, col2)
VALUES
($1, $2)
ON CONFLICT ON CONSTRAINT sample_table_pkc DO
UPDATE
SET
col1=CASE WHEN $1 IS NULL 'NULL' ELSE 'NOT NULL' END
,col2=$2
;

ケース2

INSERT INTO sample_table
(col1, col2)
VALUES
($1, $2)
ON CONFLICT ON CONSTRAINT sample_table_pkc DO
UPDATE
SET
col1=COALESCE($1, 'NULL')
,col2=$2
;

フォーマットできるケース

ケース1

SET句の項目が1つのみ

INSERT INTO sample_table
(col1)
VALUES
($1)
ON CONFLICT ON CONSTRAINT sample_table_pkc DO
UPDATE
SET
col1=CASE WHEN $1 IS NULL 'NULL' ELSE 'NOT NULL' END
;

ケース2

SET句の項目が1つのみ

INSERT INTO sample_table
(col1, col2)
VALUES
($1, $2)
ON CONFLICT ON CONSTRAINT sample_table_pkc DO
UPDATE
SET
col1=CASE WHEN $1 IS NULL 'NULL' ELSE 'NOT NULL' END
;

ケース3

SET句の項目は複数だが条件式はなし

INSERT INTO sample_table
(col1, col2)
VALUES
($1, $2)
ON CONFLICT ON CONSTRAINT sample_table_pkc DO
UPDATE
SET
col1=$1
,col2=$2
;

ケース4

UPSERTではなくUPDATEのみ

UPDATE sample_table
SET
col1=CASE WHEN $1 IS NULL 'NULL' ELSE 'NOT NULL' END
,col2=$2
;
