How to fix : In Migration, a raw query sequelize ad backslash escape in varchar which cause error while inserting that value in database

问题

The migration selects data from one table and inserts the data into another table. While inserting, the sequelize adds backslash escape in varchar 'v_occupation' value which is throwing error in insertion.

I have tried replacements and replace on v_occuption but all in vain

const queryToUpdateExistingTable = 
`INSERT INTO social_profile ( fk_user_id , fk_marital_status_id ,fk_military_service_id , v_occupation , fk_education_id , v_bio ,v_pets ,v_places_lived ) 
VALUES (:fk_user_id , :fk_marital_status_id, :fk_military_service_id, :v_occupation , :fk_education_id , :v_bio, :v_pets , :v_places_lived) 
return queryInterface.sequelize.query(queryToUpdateExistingTable, 
{type: queryInterface.sequelize.QueryTypes.INSERT,
replacements: {fk_user_id: uProfileData.id ,
               fk_marital_status_id:uProfileData.fk_marital_status_id,
                                fk_military_service_id: uProfileData.fk_military_service_id,
                                v_occupation: uProfileData.v_occupation,
                                fk_education_id: uProfileData.fk_education_id,
                                v_bio: uProfileData.v_bio,
                                v_pets: uProfileData.v_pets,
                                v_places_lived: uProfileData.v_places_lived
                            }});});

Try adding the v_occupation directly into the query string instead of using replacements. You can insert it by using + to add the strings or use Template String to insert values using placeholders in strings enclosed by backticks.

const queryToUpdateExistingTable = `
INSERT INTO social_profile 
(
    fk_user_id,
    fk_marital_status_id,
    fk_military_service_id,
    v_occupation,
    fk_education_id,
    v_bio,
    v_pets,
    v_places_lived
)
VALUES 
(
    :fk_user_id,
    :fk_marital_status_id,
    :fk_military_service_id,
    ${uProfileData.v_occupation},
    :fk_education_id,
    :v_bio,
    :v_pets,
    :v_places_lived
)`
return queryInterface.sequelize.query(queryToUpdateExistingTable, {
    type: queryInterface.sequelize.QueryTypes.INSERT,
    replacements: {
        fk_user_id: uProfileData.id,
        fk_marital_status_id: uProfileData.fk_marital_status_id,
        fk_military_service_id: uProfileData.fk_military_service_id,
        fk_education_id: uProfileData.fk_education_id,
        v_bio: uProfileData.v_bio,
        v_pets: uProfileData.v_pets,
        v_places_lived: uProfileData.v_places_lived
    }
})
